How to Mod Spec Ops: The Line

(UPDATED 12/31/24) With any text editor and an .ini file Encryptor/Decryptor, you can mod Spec Ops to change ally/enemy weapons, health values, and other settings! You can also use UPK Explorer to do texture modding and model swaps. Read on to learn more!

Getting Started

You will not need much to mod Spec Ops: The Line. Two programs are required: a text editor (like Notepad or Notepad++) and an .ini file encryptor/decryptor. You can download Rick's Decryptor/Encryptor here: https://drive.google.com/file/d/1ri8ju6x_IW_-Hqs_cqVZmqVUt-bz7UPz/view?usp=sharing.

The normal version of Notepad works fine for modding the .ini files, but if you would prefer to use Notepad++, you can download that here: https://notepad-plus-plus.org/.

If modding causes your game to experience problems, like the main menu not loading, you'll need to verify the integrity of the game files. This will restore Spec Ops to its unmodded state. This does not work for the files in My Documents/My Games/SpecOps-TheLine. Back those files up if you plan to alter them!

Later sections will require use of UPK Explorer[www.nexusmods.com].

Editing INI Files + Changing NPC Guns

You can find the .ini files for Spec Ops in Steam\steamapps\common\SpecOps_TheLine\SRGame\Config. By default, they are encrypted and will appear in a foreign language when opened.



To make them accessible, you will need to use these programs extracted from the .zip folder. All you need to do is drag an .ini file onto Gibbed.SpecOpsTheLine.IniDecrypt.exe, and it will be readable and editable.


You will see lines of code if the decryption is successful. From here, you can change whatever values you want to. Bear in mind that there is plenty I do not know about modding the game. I am not sure what will work if it is changed, or how the changes will pan out.


Let's start simple and give some different guns to enemies. How about we give the Insurgents (or Marauders, as the files call them) some better equipment?

Decrypt DefaultPawn.ini and open it up. Hit CTRL+F and search for "YPawn_MarauderAssault". It should take you down to the faction's weapon list.


The weapon list is included in the next section of the guide. For now, replace all primary weapons with "SRGame.YWeapon_AA12" and all secondary weapons with "SRGame.YWeapon_PythonElite". When you're done, the file should look something like this...


Now save the file and close Notepad. Drag the .ini file over Gibbed.SpecOpsTheLine.IniEncrypt.exe to encrypt it again. Paste it into the Config folder and replace the original DefaultPawn.ini file. The game will be able to read your modded file and give those enemies the new guns.



There we go! If you did everything right, you'll be facing down Insurgents with automatic shotguns. You can pick up an AA-12 and use it against them, too!

Weapon List

Here are all of the file names for Spec Ops: The Line's weapons. This includes guns that are exclusive to multiplayer or are not normally accessible.

Regular Weapon Names:
(These weapons will load no matter what level you are in.)

• YWeapon_M4Carbine
  
• YWeapon_SCAR
  
• YWeapon_HnKUMP45
  
• YWeapon_FNP90
  
• YWeapon_MicroUzi
  
• YWeapon_SAW
  
• YWeapon_MilkorMGL
  
• YWeapon_RPG
  
• YWeapon_BenelliM1014
  
• YWeapon_SawedOffShotgun
  
• YWeapon_AA12
  
• YWeapon_BarrettM99
  
• YWeapon_SteyrElite
  
• YWeapon_HK417
  
• YWeapon_FAMAS
  
• YWeapon_TAR21
  
• YWeapon_AK47
  
• YWeapon_DesertEagle50AE
  
• YWeapon_M9A1
  
• YWeapon_PythonElite

Multiplayer Weapon Names:
(I can't get these to load in singleplayer. Their names and ammo counts will appear if given to Walker, but the models and icons will not show up. This also applies to enemies and Adams/Lugo.)

• YWeapon_TDIVector
  
• YWeapon_MP7
  
• YWeapon_AKS74u
  
• YWeapon_Mossberg590A1
  
• YWeapon_M110SniperSystem
  
• YWeapon_MSG90
  
• YWeapon_OTs14Groza
  
• YWeapon_AK74
  
• YWeapon_Glock18
  
• YWeapon_SIGP220
  
• YWeapon_FNP45

AI Weapon Names:
(These weapons are exclusively used by allied and enemy AI. Most of them just determine the fire rate for the individual weapon. The Knife is a strange exception: allies and enemies will shoot invisible bullets with it instead of charging you, and they will not drop it when killed.)

• YWeapon_MicroUzi_Commando
  
• YWeapon_SAW_Adams
  
• YWeapon_MilkorMGL_AI
  
• YWeapon_RPG_AI
  
• YWeapon_SteyrElite_Lugo
  
• YWeapon_Knife

Scripted Weapon Names:
(These weapons are used by turrets or in special sequences. Aside from the MilkorMGL, I do not think they work when given to anyone.)

• YWeapon_MilkorMGL_Truckride
  
• YWeapon_M2E2HMG
  
• YWeapon_HumveeGun
  
• YWeapon_HumveeGunDFA
  
• YWeapon_TurretMiniGun
  
• YWeapon_TurretMiniGunOnFlight
  
• YWeapon_HeliGun
  
• YWeapon_Mk47Striker
  
• YWeapon_Mortar

Unusable Weapon Names:
(These do not load at all. DummyWeapon3 makes the screen appear black if put in a level.)

• YWeapon_TestWeapon
  
• YWeapon_DummyWeapon1
  
• YWeapon_DummyWeapon2
  
• YWeapon_DummyWeapon3

Giving different guns to Walker will only affect him in Chapter 1's intro. When he reaches the first encounter with the Insurgents, he will switch back to his usual M4A1 and M9. Adams and Lugo can use different weapons normally, but replacing Adams's shotgun may cause some glitches in door-breaching sequences. Having Adams and Lugo stealth-kill enemies will make them revert to their normal guns as well.

Altering Health Values

You can change the health values for Walker, his allies, and enemies in the DefaultPawn.ini file. You can also modify the health regeneration rate for characters along with other traits.



The stats for different characters and enemies are listed as...

• SRGame.YPawn_Walker
  
• SRGame.YPawn_Adams (chapters 1-12)
  
• SRGame.YPawn_AdamsAlone (chapters 13-14)
  
• SRGame.YPawn_Lugo
  
• SRGame.YPawn_Enemy (regular 33rd enemies)
  
• SRGame.YPawn_EnemyMarauder
  
• SRGame.YPawn_EnemyElite
  
• SRGame.YPawn_HeavyTrooper
  
• SRGame.YPawn_Commando

Simply edit the values however you want them, making characters as overpowered or as weak as you want.

Note that this will only affect Combat Op difficulty. To change health values in other difficulties, you will need to modify DefaultPawnEasy.ini, DefaultPawnHard.ini, or DefaultPawnInsane.ini. These are for Walk on the Beach, Suicide Mission, and FUBAR difficulties respectively.

Changing Weapon Stats

To change how weapons work in Spec Ops, you need to edit the DefaultWeapons.ini and SRWeapons.ini files. DefaultWeapons.ini is only present in the Config folder of Spec Ops: The Line in Steamapps. The SRWeapons.ini file needs to be changed in two places: in Steam\steamapps\common\SpecOps_TheLine\SRGame\Config, and in Documents\My Games\SpecOps-TheLine\SRGame\Config.



(Pictured: an M9 with 10 bullets per magazine instead of 15, longer effective range, and higher damage per shot.)

If all of these files have been changed, then the weapon stats will correctly appear. Not changing one of them will cause the altered weapon stats to not show up properly. It is easiest to notice when changing magazine sizes or damage. You can adjust the effective range, whether a headshot causes an enemy's head to explode, how much ammo you get on pickup, and many other options for each gun!

Here is a semi-complete list of stats for the guns of Spec Ops. Special thanks to monoculusRift for sharing it in the comments!
https://docs.google.com/spreadsheets/d/1j-BNe3GeF3Dks4q42tkfbSNpVD1k1sWgoi1zDGm2LAk/edit


(Pictured: an AK-47 with 45 bullets per magazine being used to execute a 33rd soldier.)

Some weapon stats have straightforward names, like m_damage, but others deserve clearer explanations. Note that these can be added to weapons that don't include the stat by default.

• m_refireInterval = Fire rate for the weapon.
  
• m_refireIntervalAudio = Rate for the gunfire sound.
  
• m_maxAmmoCount = Magazine size.
  
• m_startAmmoCount = Ammo you start with when the gun is picked up; this usually matches the magazine size.
  
• m_tacticalReloadEnabled = True gives the gun an extra bullet when you reload a partial magazine, while False makes the gun always reload to its normal magazine size. The .44 Magnum and M32 MGL have this set to False.
  
• m_causeHeadshotSound = Plays a distinct sound when you shoot an enemy's head.
  
• m_makesHeadExplode = Headshots blow up the enemy's head instead of just killing them.
  
• m_alwaysRaised = The crosshair is always visible even when the gun isn't being aimed. This is used by the shotguns.
  
• m_pawnSpeedModifier = Affects how fast or slow characters move with this weapon. Normal speed is 1. Anything below that slows the character, and anything higher than that makes the character faster.
  
• m_maxWeaponRange = The farthest distance at which the gun can deal damage.
  
• m_rangeOfMaxEfficiency = The farthest distance at which the gun will do its maximum damage.
  
• m_oneHandWeapon = Does nothing. Weapons with this stat are always set to False.
  
• m_refireType = Decides what the gun's fire mode is. This is used by Assault Rifles, SMGs, and the Glock 18. The options for this setting are straightforward: YRFT_SingleShot, YRFT_FireBursts, and YRFT_Automatic.
  
• m_burstFireRounds = Sets how many bullets are shot from a single trigger pull from a burst-fire weapon.
  
• m_burstRefireDelay = Sets how much time has to pass between shots of a burst-fire weapon.
  
• m_doesSilencedShots = Sets whether the gun is considered silenced or not. True makes gunshots silenced, and False makes them normal and audible to enemies.

Menu and HUD Text Changes

Changing the way that guns, difficulties, and missions are named is fairly simple. You don't even need the ini decryptor/encryptor to do this! All you need to do is to edit the SRGame.INT files in 2 locations:

• Steam\steamapps\common\SpecOps_TheLine\SRGame\Localization\INT
  
• Documents\My Games\SpecOps-TheLine\SRGame\Localization\INT

From there, you can use CTRL+F to search for the text you want to change. Some names come up more than once, so you will need to change all instances of it on both files to make sure that your changes appear. Back up the version in My Games, as it will not be affected by verifying the game's files on Steam.



As an example, I will change the Normal difficulty to "Born Again," complete with a new description. Some other difficulty name/description changes can also be seen above.



There is also a lot of unused text in the files, including earlier mission descriptions and cut mode rules. You can ignore these pieces of text.

UPK Explorer and Modding

You can go further with modding Spec Ops using the program UPK Explorer. It allows you to open .upk file, extract textures, change which models are assigned to which characters in levels, and inject your own custom textures into the game!

You can download the program from Nexus Mods here: https://www.nexusmods.com/site/mods/587/?tab=logs

If you do not have an account with Nexus Mods, an alternate download link is below. Note that it is outdated compared to the most recent Nexus build: https://cdn.discordapp.com/attachments/833782014112956469/1128037667683176458/UPK_Explorer-587-2-0-2-0-1687283476.zip

To get started with UPK Explorer, start the program and choose the option to create a working folder. This is where textures will be extracted to, and where your custom textures will be imported from. Any folder works for this. When it is chosen, it should look something like this...


Exports are where extracted textures are placed. Imports are where you put textures you want to inject into the game.


From here, you should choose a .upk file from Spec Ops: The Line's Steam Folder. They can be found in Steam\steamapps\common\SpecOps_TheLine\SRGame\CookedPCConsole.


What you should do from here depends on your plans for the game. Do you want to extract its textures for your own use? Maybe you would want to edit a .upk file's model assignments? Or would you like to insert your own textures into a .upk file? The next few sections will cover each option.

Other Useful Info

Texture and model changes carry over between levels and level segments as long as you are playing the game in a single session. As an example, modifying the Insurgents to look like corpses in the first .upk file for Chapter 2 would affect ALL of Chapter 2 as well as Chapter 3 - as long as you continue playing from that point. Quitting the game after Chapter 2 and returning would make Chapter 3 appear normally.

Some characters, primarily cutscene-related ones, need all of their _K level files modified for their changes to appear properly, so remember that when modding characters like McPherson or Konrad. Not all models are rigged for the same functions, so you might need to use Blender to rename or assign bones to characters or guns.

In theory, you could reduce the amount of work needed by only changing the first appearance of an enemy type per level. Some levels have enemies show up later (like the 33rd only appearing after the halfway point of Chapter 4), so it isn't a perfect solution.



For reference, .upk files usually follow a specific naming convention. Files ending in _P contain Walker, Lugo, and Adams. Files ending in _K contain enemies, props, and other NPCs.

Here's a list of which level is tied to which .upk files:

• SP_Desert = Initial chapters where you fight Insurgents (chapters 1 and 2).
  
• SP_Atrium = Last battles with Insurgents, encounter with Agent Kastavin, first fights with 33rd (chapters 3 and 4).
  
• SP_Gorge = Search for Agent Daniels, meeting Agent Gould (chapters 5 and 6).
  
• SP_CityGate = Saving Gould, White Phosphorus level (chapters 7 and 8).
  
• SP_Road = First talk with Konrad, sniper choice (chapter 9).
  
• SP_StealingWater = Working with Agent Riggs (chapter 10).
  
• SP_DollsHouse = The Mall (chapter 11).
  
• SP_RadioMan = Tower battles, confrontation with Radioman (chapter 12).
  
• SP_ShipsGraveyard = Post-crash, Walker reunites with Adams, civilian choice (chapter 13).
  
• SP_Bridge = The Bridge (chapter 14).
  
• SP_BurjDubai = Final level and choices (chapter 15).
  
• SP_Epilogue = Epilogue chapter and choices.

UPK File Names and Meanings

Most of the UPK files in Spec Ops can be found in Steam\steamapps\common\SpecOps_TheLine\SRGame\CookedPCConsole. They're grouped together based on what role they serve, and knowing what they do will help you skip the unnecessary ones or get right to what you need.

File Prefixes in CookedPCConsole

• AIFeedback - Contains data relating to voice lines and their triggers. The ones ending in _LOC_INT contain the actual voice lines; see my audio extraction guide for getting those out of the files.
  
• CHn - Model and textures for a multiplayer customization part. Files listed as CHn_DM are for the Damned multiplayer faction, while CHn_EX are for the Exiles faction.
  
• MP - Multiplayer map data.
  
• PR01 - A model and textures for pre-order multiplayer customization content. It is also divided up by DM for the Damned and EX for the Exiles. It is not available by default, though the models can be imported into other UPK files, and you can unlock them using another guide.
  
• SP - Singleplayer map data. The ones ending in _LOC_INT contain voice lines.
  
• YGAMEINFO - Data for the various game modes and menus. The ones ending in _LOC_INT contain voice lines. They contain abbreviations of their own.
  --DM means Chaos Mode,
  --HD means Hold and Destroy,
  --OFFLINE means Uplink,
  --RP means Rally Point,
  --SP means Singleplayer,
  --SW means Spoils of War (unused),
  --TDM means Mutiny,
  --TE means Attrition, and
  --TESTMPUPLOAD just contains an unused model of an XM8.

SRGame is always loaded, no matter which mode you are playing. The multiplayer weapons appear in each mode's YGAMEINFO file, meaning that you will need to change all of those if you want to make a modded multiplayer weapon appear in all MP modes.

Startup_INT contains the HUD icons for Spec Ops, including its weapon icons, multiplayer icons, and mission objectives. Like SRGame, Startup_INT must be replaced for changes to appear; a copy cannot be placed in the DLC folder to make modified icons show up.

Texture Extracting and Replacing

You will need to download GIMP, an image-editing software, for part of this guide. Check out the website here: https://www.gimp.org/

The textures of Spec Ops: The Line are stored around its .upk files and used depending on what level you are in. The SRGame file (containing models and textures for singleplayer weapons) is always loaded regardless of where you are. Enemy textures have the same names across different files, and they sometimes carry over into different level segments.

To extract a texture, simply load a .upk file and pick a file to export. The textures are mostly broken up into 3 files, ending in _D, _N, or _S. You'll notice the most differences from changing the _D file.


For an example, here is the AA-12's weapon texture. Press the "Export DDS" button to extract it. When you check your Exports folder, you will find it there.


Here are the 3 main textures extracted into the Export folder. They most often end up in a subfolder called "PF_DXT1". You should create a folder with the same name in the Import folder, as that is where your custom textures will go.

To make sure that the game accepts your custom textures, you need to make sure it has the same name as before and the right minmaps. The latter is simple - load the texture into GIMP, select "Export As...", overwrite the existing file, and use the settings listed below to export it.


After you are done, place the custom texture in the PX_DXT1 folder in your Import folder. Open UPK Explorer and select the .upk file you need - SRGame, in this case - and go to the Inject Textures tab. If you did everything correctly, your custom texture should appear in the preview area. When you are ready, press the "Inject Textures and Save a Copy" button. This will create a copy of the .upk file with your custom textures. The program will tell you to close the current package.


You can edit other .upk packages or close UPK Explorer from here. Back up the original .upk file if you haven't already. After that, rename the copied .upk to match the original file name.

If all goes according to plan, your custom texture should appear in game!



Note that you can inject more than one texture at once, but this can only be done for one .upk file at a time.

Model Swaps with UPK Explorer

The models within .upk files can be swapped around if certain functions are present. This can mean giving the 33rd the models of civilians, turning cutscene characters into enemies, or swapping around allies and enemies. The important thing to remember is that these models MUST be in the same .upk file. Adding models from another .upk file is covered in the next section.


As a reminder, .upk files ending in _K often contain enemy/NPC/prop models, while .upk files ending in _P contain player/squad models. Models that end in _SK have skeleton animations and usually work when replacing enemies and NPCs. Lugo's hat is stored in the SRGame.upk file, so you will have to edit that if you want to replace or retexture it.


To get started, load up a file in UPK Explorer and go to the "Edit package" tab. Select the "Objects" tab and scroll through it. You're looking for data starting with Default that relates to the character you want to change. For our example, we will replace Walker and Adams with Lugo's model.


Go to SRAssets and find the data containing the m_charactermesh entry. This determines which model is assigned to which character. If the model exists in the .upk file, it can be used to replace another model. Click on the button with the 3 dots, scroll until you find Lugo's model, and select it.


When you are done, save your changes and close the package. You can edit other .upk packages or close UPK Explorer from here. Remember to back up the original file and rename the copied file to match the one it will be replacing!


If done right, you should be playing as Lugo and have Adams replaced with Lugo. The voice lines will not be changed, though.


Trying to replace a character model with another type of model (a prop, a static corpse without the _SK name, etc.) will instead make the Dummy Character appear. He is an all-blue, featureless man in a suit. He should still function as an ally or enemy, though, since he is rigged for animations.

Swapping Models Between .UPK Files

Through the process is more complicated, it is possible to replace models using different UPK files, like turning Lugo into the Radioman or adding Chapter 9's monorail to Chapter 1. This requires version 2.0.3.0 of UPK Explorer or better to pull off, so make sure you have the right build of it before continuing!

For an example, we will replace Walker with Konrad's model in Chapter 1.


First, click development at the bottom of UPK Explorer. After that, open YGAMEINFO_COOP_CONTENT_SF.upk.


Click EDIT PACKAGE at the top, then click on Objects then look for Konrad's model here.


Click Export on the top right above the model. That is Konrad's character mesh, basically his model. Go back to the Extract Textures tab and grab the 6 for Konrad.


(The bottom 6 there.)

Export those as DDS, as we will need those to replace Walker's. Open the SP_Desert01_p.upk file and look at Walker's textures, grab the names (or export them to get them), and convert and replace them with Konrad's 6 textures.


After doing this, click on Edit Package and direct your way to the MC_PLAYER mesh. This is Walker's model/character mesh.


Click IMPORT and find Konrad's mesh. The red text will appear because Konrad isn't Walker and is missing animations, so we will be taking Walker's. Missing ones appear red, so next to the box click the ... and add any of his faces in there. I just used FACE_THRO but any should be fine


Under Object References at the top, you will get 4 more red boxes.


The first one is EYES, so we need Walker's eye animations, so click the ... and then Export then find Walker's eyes under MC_EYES.


Do that for all 4, just find what its looking for on the left and replace it with the CH_PLAYER one
then click OK.


From there, choose SAVE COPY and you are done!


If you did everything right, Walker should appear as Konrad throughout all of Chapter 1! Some of his animations might appear a little odd due to their proportions being different, but he will function fine otherwise.

Changing the Player's Starting Weapons

Aside from Chapter 1, the player's starting weapons are set via data in a level's _P file. This is also where the models for Walker, his squad, and the co-op characters are located.



You need to edit the section "YSeqAct_ModifyArsenal" in the _P file. It can be found under "TheWorld" then "PersistentLevel" and then "MainSequence". The number after ModifyArsenal varies depending on which character is being given weapons and when it happens.


You can add weapons that aren't normally in the level, including the Bayonet Runner's Knife! This can be done in campaign and in co-op. Sadly, multiplayer-exclusive weapons still won't work.

Creating a Removable Mod Folder

Spec Ops is set up to prioritize UPK files in a specific part of the game's directory. The UPK files placed there will be loaded in place of the main game's files and can be removed along with the folder. Setting this mod folder up will make it so you won't have to constantly overwrite the main game's UPK files!

The folder should be created in Steam\steamapps\common\SpecOps_TheLine\SRGame\DLC\PCConsole\DLC1. You can name it anything - as an example, I used the name of my mod Eternal Penance for this folder.



Almost any UPK files can be placed in here, and they will be loaded instead of the regular files in Steam\steamapps\common\SpecOps_TheLine\SRGame\CookedPCConsole. However, the SRGame.upk file will not work in this folder. You have to overwrite the version in CookedPCConsole for the changes to load.

Useful Model Locations

Some character and gun models can only be found in certain .upk files. In case you want to extract these models or use them, the names of these useful .upk files are included below.

• Lobby.upk - Beta gun models (417, AA-12 AK-47, RPG, TAR-21, UMP-45, and W1300)

You can also extract the co-op character models, though these are located in their own folder. You can extract them from the .upk files in Steam\steamapps\common\SpecOps_TheLine\SRGame\DLC\PCConsole\DLC1.

• COOP-Garage_P.upk - Tactical solder, Heavy soldier
  
• COOP-GorgeTop_P.upk - Sunglasses and mask soldier, Scavenger soldier
  
• COOP-SGY_P.upk - Fremen soldier, Hunter soldier

Multiplayer outfits can also be extracted, but their lack their own head models. They still work as character replacements, but they will appear with empty spaces where their custom heads would be.

Quirks of Each Faction

The various enemies and characters you encounter in Spec Ops have different attributes that can make them easier or tougher to mod. Let's go over each one and check out their pros and cons!

Insurgents/Refugees

• The Insurgents have 6 models in total.
  
• They have unique textures applied to their models that are designed to give them clothing variety. It looks fine on their own models, but it can look strange on other models (like Civilians). One solution is to give the replacement models darker textures, as the new colors won't appear as much that way.
  
• The 6th Insurgent model has a wounded variant seen in Chapter 7.
  
• The 2nd Insurgent's model is used for Fari in Chapter 3.

Regular 33rd Enemies

• The standard 33rd enemies have 5 models in total.
  
• They wear a combination of different headgear: a headset, sunglasses, a cowboy hat, a baseball cap, and/or a patrol hat. These fit some models but not others, so keep that in mind or replace the headgear models when changing them.
  
• Their bodies are used for Lt. McPherson in Chapter 4 and the Interrogator in Chapter 7.
  
• They have special wounded models used after Chapter 8's mortar scene.

Medium 33rd Enemies

• Medium 33rd enemies have 3 models in total.
  
• A unique Medium enemy without a helmet can be seen in Chapter 15, but he never appears in combat or outside of that scene.

Zulu Squad

• Zulu Squad enemies have 4 models in total.
  
• The bald Officer seen in Chapter 14's outro and Chapter 15 uses the regular Zulu Squad model for his body.

Falcon One

• Falcon One enemies have 2 models in total.
  
• They have a special wounded variant that appears in the ending where Walker kills the rescue team.

Special Units

• Bayonet Runners have 4 pieces of headgear: a mohawk, a headset, sunglasses, and a beret.
  
• The Sniper's model is also used for 33rd enemies with RPGs and Grenade Launchers.
  
• Heavies have visors that can take damage and break from multiple gunshots.

Civilians

• Female Civilians have 4 models, not counting crowd or cinematic variants.
  
• Male Civilians have 6 models, not counting crowd or cinematic variants.

Unstable Models

Not every model can perfectly take the place of another. From my experiences, these models have issues when they are replacing something or being replaced. The specific issues are listed with the model.

Crowd Civilians

• CH_CROWD_MALE_001
  
• CH_Civilian_Male_02.CH_Civilian_Male02_crowd
  
• CH_Civilian_Female_04.CH_Civilian_Female_04_crowd

Most of the civilians in Spec Ops work fine as player characters, NPCs, or enemies. The Crowd variants are meant to be hidden away in scripted sequences, fleshing out the numbers of a scene without stressing the engine. They stretch out when killed and struggle to correctly fire their weapons. They also have the chance to crash the game when used outside of their usual appearances.

Daniels' Corpse

• CH_CORPSE_Electrocuted_SK

Daniels can move around and animate when his body replaces another character. However, that's the best you can get out of him. He can't aim or properly fire weapons, and the chance of his model crashing the game is pretty strong.

Heavy Troopers

• CH_ENEMY_KONRAD_HEAVY_SK

The best you can do is replace the textures of a Heavy Trooper. Replacing its model will crash the game as soon as the level loads. Trying to use its model to replace another character causes the same crash. Maybe it has something to do with their helmet model or bones? Regardless, they should be left alone.

Bayonet Runners

• CH_ENEMY_KONRAD_COMMANDO_SK

Bayonet Runners mostly work well when they replace your character or another character. Trying to replace them will cause a crash as soon as they load. This is likely due to their unique leg-rolling bones, which other models in Spec Ops do not have.

Debug Modes

DAMAGE DEBUG MODE

You can activate the debug mode for damage notifications in DefaultGame.ini by setting m_debugMode to true instead of false. This will let you know how much health Walker has, how much damage he has taken, and where the damage is coming from.



When activated in-game, it looks like this:

UI DEBUG MODE

The user interface for Spec Ops has a debug mode of its own. It doesn't do much outside of show you the coordinates for your mouse and what each selectable item does. It also keeps the mouse visible during gameplay.



Go to DefaultUI.ini and set bRenderDebugInfo to true instead of false. This will enable the UI debug mode. It looks like this when it is active:

Cut Content and Strange Stuff in Spec Ops' Files

In my time reading through and editing the game's files, I have found unusual things that could not be explained. Some of this is speculation and conjecture on my part based on clues left behind in the game files. I'll list these oddities below:

SHIPWRECK AND FORECLOSURE MAPS

These two multiplayer maps were featured in a console-exclusive beta, but they are not in the final version of the game (as far as I know). There are still plenty of references to them, with Shipwreck being called "Tanker" and Foreclosure being called "Tower".



They were clearly finished enough to be featured in the multiplayer beta for the game, but I haven't found their map files in the final release. Their loading screens are still present in the Movies folder, though!

CHILD CIVILIANS

In addition to male and female civilians seen in-game, there is a reference to child civilians being in Spec Ops. There are signs of children formerly being around the refugee camps in chapter 4, and a burnt child appears after the White Phosphorus bombing in chapter 8, but none others directly appear in-game.

HORDE MODE

There are lots of references to a "Horde Mode" scattered throughout the .ini files. It is unclear whether it is another name for an existing mode or a cut survival-based mode. Judging by what I've found, it would involve Walker, Adams, Lugo, and Riggs fighting off enemies.





I have not found a way to enable the mode so far. There is also a reference to a level called "HordeCity" among the level names. Whether it was was cut before completion, or if it was made but scrapped like Foreclosure and Shipwreck, is unknown.

"JIM" MULTIPLAYER KIT

For some reason, a kit option called "Jim" for the Exiles Gunner was completed but made unobtainable. The developers noted that it wasn't being used anymore in the game's code.



The model and textures apparently still exist in the game. You can actually restore this kit by modifying the DefaultGame.ini file!

THE MISSING FLAMETHROWER

In pre-release footage for Spec Ops, Walker can be seen using a Flamethrower. Unlike the AUG in the game's CGI trailer, this appeared to be used in normal gameplay. The development team also made models for a Heavy Trooper that would use a Flamethrower[www.artstation.com] for a DLC that never got released.





There are some references to it in the SRGame.int localization file. In particular, there are lines mentioning a regular version and an AI version.

OTHER UNUSED GUNS

The SRGame.int file lists a number of unused guns that, as far as I know, aren't present in the final game. Here are all the entries that I know of:

• [YWeapon_HuntingRifle]
  m_ammoName=Hunting Rifle Ammo
  m_weaponName=Hunting Rifle
  
• [YWeapon_AT4]
  m_ammoName=AT4 Ammo
  m_weaponName=AT4
  
• [YWeapon_Machinegun]
  m_ammoName=MG Ammo
  m_weaponName=PKM A Machinegun

The AT4 is an American rocket launcher, and the PKM is a Russian general purpose machine gun.

EXODUS CO-OP CAMPAIGN

In SRGame.int, there are tons of references to a co-op campaign called "Exodus," where you would play as Grey Fox before Delta arrived in Dubai. There are mentions of leaderboards, level names, and a basic story outline to follow!

MISSING MULTIPLAYER MODES

There are several cut multiplayer modes referenced in the game files, some of which got far enough along to have their own .upk files in the final game! Their descriptions remain in the localization files, so we can know for sure what they were about. They are called Spoils of War, Offline, Chopper Attack, and Special Delivery. Modified versions of the modes would have been available as NoPerks and Hardcore.



You can get Special Delivery to load in the menu, but picking them will crash the game. You can also spawn into a Spoils of War game, but none of the loot items will load. The Radioman will use his unique announcer lines for the cut mode, though!


Who knows, maybe these modes could be restored someday with enough edits to the .ini and .upk files of the game...

Closing Notes

This is still unfamiliar territory for me. Any insight you all can provide on modding this game would be greatly appreciated! Spec Ops seems like a ripe opportunity for modding, and I hope this guide brings more attention to the fact that it can be modified to some degree.

[Yossarian the Assyrian]

I'm not sure. In theory, sure, but I don't know much about camera modding.

[>:(]

would it be possible to use this to center the character in the middle of the screen both walking and aiming?

[SniperSamir]

ohh okay thank you

[Yossarian the Assyrian]

@SniperSamir

The YFMODResource_VSB file contains gun sounds. The automatic ones are tougher to extract, though - I haven't found a way to directly do it. I had to record them in-game as a workaround.

[SniperSamir]

Which sound files are the gun sounds?

[Yossarian the Assyrian]

@Отель Красный

Do you remember which chapters the bug happened in? I can try to fix the mod.

@DANILLO

Thanks for letting me know. I just updated the link.

[DANIILLO]

Thank you for the work done.

Decryptor/Encryptor broken link

[Отель Красный]

I have a bug of textures with Squad Replacement Mods 1 Exile skins, screen for example https://disk.yandex.ru/d/imDGwY07a7ECpw can anyone help me with it ?

[Yossarian the Assyrian]

Same! Spec Ops is a classic for me. It deserves every bit of praise it gets.

[MJ]
