The Counter-Strike: Condition Zero Custom Mission System
By GGwpAiushtha
The Custom Mission System allows users to create their own Missions for use with Counter-Strike: Condition Zero. These Mission Packs may include new maps, new challenges, new bot personalities, new bot skins, and so on.
The Layout of a Mission Pack
Mission Packs are found in the czero\MissionPacks folder. Each Mission Pack must have its own uniquely named folder.

Below is an example file listing for a Mission Pack called "MyMission":


This file defines includes information such as the mission description, what team the player is on, which bot personality file to use, and so on.

The Overview.tga is a 24-bit image displayed as part of the Mission Pack's "splash screen". It must be no larger than 256x256 and is scaled into an area that is 320x68 at a screen resolution of 640x480.

Easy.vdf, Normal.vdf, Hard.vdf, Expert.vdf
These files define the game rules, map progressions, available teammates, enemies, and per-map challenges. If these files are missing, the corresponding CareerGameEasy.vdf, areerGameNormal.vdf, CareerGameHard.vdf, and CareerGameExpert.vdf files from the czero folder will be used.

This file defines bot personalities for use as teammates and enemies in the Mission Pack.
The Overview.vdf File
Below is an example Overview.vdf file in its entirety:

"Author" "Turtle Rock Studios"
"Title" "My CZ Mission"
"Description" "This is my custom mission pack for CZ."
"URL" ""
"SoloPlay" "1"
"CoopPlay" "0"
"Team" "CT"
"BGColor1" "47 62 90"
"BGColor2" "0 0 0"
"TextColor" "255 255 255"
"BotProfile" "BotProfile.db"}

Author: The author of this Mission Pack
Title: The title of the Mission Pack
Description: A colorful description of the mission
URL: A website related to this Mission Pack, often the author’s home page
SoloPlay: Unused but reserved for future utilization
CoopPlay: Unused but reserved for future utilization
BGColor1: Red, green, and blue (RGB) values between 0 and 255 that define the background color used for the Mission Pack user interface screens
BGColor2: Unused but reserved for future utilization
TextColor: RGB color values used for some Mission Pack text
BotProfile: The filename of a file containing the roster of bot personalities to use with this Mission Pack
The Easy.vdf, Normal.vdf, Hard.vdf, and Expert.vdf Files
These files define the game structure. Each file corresponds to the difficulty selected by the player. In other words, if the player starts your mission with a difficulty of “normal”, the Normal.vdf file will be read.

It is highly recommended that you examine the CareerGame*.vdf files. They contain the data for the standard CZ Counter-Terrorist Tour of Duty.

InitialPoints: The number of Reputation Points the player starts the game with.
MatchWins: The minimum number of rounds a team must win in order to win a match.
MatchWinBy: The number of wins a team must lead by in order to win a match.
Characters: A space-separated list of bot names defining the roster of teammates that can be purchased with Reputation Points. These bot names must have corresponding personality definitions in the bot database (ie: BotProfile.db).
CostAvailability: Each teammate has a Reputation Point cost, from 1 to 5. This section defines how many total Reputation Points the player must have to “unlock” each cost level of teammate. For example, a pair of numbers such as “4” and “15” means that the player must have at least 15 Reputation Points to unlock cost 4 teammates.
Maps: The set of maps used in this mission. The name of each map section must match a bsp file located in czero\maps, cstrike\maps, or valve\maps. See the “Defining a Location (Maps)” section for more information.
Defining a Location (Map)
Maps are organized as “triplets”, or sets of three maps. The first, second, and third maps form the first Tour of Duty, the fourth, fifth, and sixth are the second Tour of Duty, and so on. All three maps in a Tour of Duty must be won in order to unlock the next Tour of Duty.

“map name”
“bots” “<list of enemy bot names>”
“minEnemies” “<count>”
“threshold” “<value>”
“tasks” “<list of tasks>”
“FriendlyFire” “0” or “1”
“commands” “<console command string>”}

“map name”
The filename of the bsp to load for this location without the .bsp extension. For example, “de_dust_cz”.

This field is followed by a string containing a list of enemy bot names for this map. Bots are added from left to right, in order. For example, the list “Joe Fred Alex Barney” would look up “Joe” in the missions bot database and add a bot with those parameters first, followed by “Fred”, “Alex”, and “Barney” up to the desired number of enemies for that location.

This value defines the minimum number of enemies the player will face on this map.

This number defines the Reputation Point value above which one enemy is added for every additional Reputation Point until we run out of bots on the “bots” line.

This field defines a list of tasks/challenges the player must complete to win this map. Each task, and that task’s parameters, must be enclosed within single quotes within the overall string. For example:

"tasks" " 'kill 7' 'kill 2 survive' 'winfast 60' "

For a full list of tasks, see the Task Reference section.

If this is set to zero, friends cannot be hurt by each others weapons. If “FriendlyFire” is “1”, friends can hurt each other.

The “<console command string>” is sent to the console when the map is loaded. This can be used to change system parameters just as if the user had entered the string in the console. Note that certain commands (ie: mp_startmoney) don’t function, as they are reset by the system after these commands have been given.
Task Reference
For each task listed below, required parameters are enclosed in < >, and optional parameters are enclosed in []. Multiple optional parameters are separated by a vertical bar.

The optional parameter “survive” means the player must complete the task in a single round without being killed. The optional parameter “inarow” means the player must complete the task over potentially several rounds without dying.

Defining Preview Images for a Location
Each location requires two “thumbnail” images for display in the interface.

The first one is the small square image used for the location’s button within its Tour of Duty. The second is the large preview image displayed when a location has been clicked on by the player.

The small button image must be a Targa image (.tga) that is 128 pixels wide and 128 pixels tall, with a filename identical to the map’s bsp file (except, of course, for the .tga extension). Place this image in the folder: czero\gfx\thumbnails\maps

The preview image must be a Targa image that is 256 pixels wide by 110 pixels tall, again with a filename identical to the map (with a .tga extension). Place this image in the folder: czero\gfx\thumbnails\maps_wide.

Note that Steam users may have to create these folders if they do not exist.

For example, if the map de_mymap_cz.bsp was used in a mission, the following two images would need to be present:


Defining Bot Personalities
Defining a bot personality consists of specifying values for a bot’s various attributes and labeling the values with a name, such as “Fred”. These attributes influence and control different aspects of a bot’s behavior, such as how observant they are, or how well they can aim their weapons.

While fairly straightforward, a bot personality database does contain a lot of data. It is strongly recommended that interested players refer to the BotCampaignProfile.db and BotProfile.db files which contain the bot personalities for the retail game.

Data within a bot database is always contained within a data block which has the following form:

<data block type> [<data block name>]
<attribute> = <value>
<attribute> = <value>

<attribute> = <value>

<data block type> can be:

This data block defines default values for all attributes.

Skin <skin name>
This data block defines a “skin” (player model) for later use. It can contain a single attribute of “Model” which should be set to the name of the .mdl file without its extension. The example below defines a skin for czero\models\player\arctic.mdl:

Skin TerroristSniperSkin
Model = arctic

Template <template name>
Templates define values for a related set of attributes. Templates are then used by specific bot data blocks to “inherit” data values. See the Data Inheritance section for more information.

<template name>[+<template name> …] <bot name>
Defining a data block via the use of one or more template names creates a bot definition. The values the bot’s attributes receive are “inherited” by starting with the values in the Default data block, and then overwriting any attribute values found in the template blocks listed, evaluated from left to right.
Attribute Reference
Value: A string. If the name contains spaces, surround it with quotes (ie: “Cliffe”)

Description: The bot’s name.

Range: 0 to 100
Description: Defines the overall “skill” of the bot. Low skill bots have terrible aim and don’t look around very much, whereas high skill bots can have extremely good aim, try to check as many corners and hiding spots as they can, and know subtle things like using the knife to run faster, switching to the pistol when out of ammo, and so on.

Range: 0 to 100
Description: Determines how aggressively a bot behaves. High aggression bots pay less attention to “danger” (ie: where teammates have died previously), are more likely to rush, and less likely to retreat. Low aggression bots are just the opposite.

Range: 0.2 to 0.5 seconds
Description: Determines the reaction time of a bot. A bot’s “reaction time” is the delay between when a visual or audio event occurs and the bot becomes “aware” of it, and can begin to act upon it. This simulates the time it takes a human to process incoming stimuli and become “conscious” of it.

Range: Seconds of time before bot will open fire after acquiring a victim
Description: After a bot has become aware of an enemy, this duration must also elapse before it will begin firing upon its victim. This attribute is primarily used for easy bots, allowing novice players additional time to react and aim their weapon before the bot opens fire.

Range: 0 to 100
Description: Defines how cooperative and “team oriented” the bot is. High teamwork bots are more likely to obey radio commands and stay with their teammates. Low teamwork bots tend to “go rogue” and do their own thing.

Value: “none” or a buy alias such as “m4a1”
Description: Defines the bot’s weapon preference. A bot can have many WeaponPreference definitions in a row, specifying a prioritized list (earlier ones are favorite over later ones) of weapons the bot will try to buy or pick up from the ground. A preference of “none” will cause the bot to buy a random weapon.

Description: Defines the difficulty categories where this bot is used. Note that these flags can be combined, such as “NORMAL + HARD”, meaning the bot can be used on either the Normal or Hard difficulty setting.

Value: 85 to 120 (100 is unshifted)
Description: Defines the pitch shift value this bot will use for its “chatter”. Lower values create lower pitched voices.

Value: 0-4 or <skin name>
Description: Defines which “skin” to select when the bot joins the game. Values 1 through 4 map to the associated skins on the player menu in game. A value of 0 selects a skin at random. If a <skin name> is given, the skin must have been previously defined using a Skin data block. Skin data blocks can refer to custom skins other than the default CZ skins. Custom skins should be placed in czero\models\player\<skin name>\<skin name>.mdl.

Data Inheritance in the Bot Database File
Defining a bot personality involves specifying a dozen or more parameters. If you want to create several bots, this means defining quite a lot of data. To help organize and modularize this bot personality data, the Bot Database makes use of a very simple data “inheritance” mechanism.

Here is an example of how the inheritance mechanism works:

Color = Grey
Shape = Circle
Size = Medium
Weight = Average
Material = Wood

Template RedSquare
Color = Red
Shape = Square

RedSquare MyRedSquare
Size = Small

The “Default” entry defines initial values of all attributes, in this case “Color”, “Shape”, “Size”, “Weight”, and “Material”. The next entry is a “Template”, which defines a data type named “RedSquare” that sets the attributes “Color” and “Shape” to “Red” and “Square”, respectively. Finally, the last entry actually instantiates an object of type “RedSquare” called “MyRedSquare” which sets “Size” to “Small”. The resulting values for “MyRedSquare” are:

Color = Red
Shape = Square
Size = Small
Weight = Average
Material = Wood

“Weight” and “Material” remain at their default of “Average” and “Wood”, since neither “RedSquare” or “MyRedSquare” changed them.

The bot database allows for a crude form of “multiple inheritance” as well:

Color = Grey
Shape = Circle
Size = Medium
Weight = Average
Material = Wood

Template RedSquare
Color = Red
Shape = Square

Template BigAndHeavy
Size = Large
Weight = Heavy

RedSquare+BigAndHeavy MyBigRedSquare
Material = Iron

In this example, a new entry has been added called “BigAndHeavy” which sets the attributes “Size” and “Weight” to “Large” and “Heavy”. Notice that the instance of “MyBigRedSquare” now lists both “RedSquare” and “BigAndHeavy” as its type, combined with the addition symbol “+”. The final values of “MyBigRedSquare” are:

Color = Red
Shape = Square
Size = Large
Weight = Heavy
Material = Iron

“Color” and “Shape” were inherited from “RedSquare”, “Size” and “Weight” from “BigAndHeavy”, and “Material” was set directly by the definition of “MyBigRedSquare”. Any number of basic types can be “added” together in this way.

With multiple inheritance, data is copied to the object in a left to right order. If both “RedSquare” and “BigAndHeavy” had values for the same attribute, the final value would match the one in “BigAndHeavy” since it came after “RedSquare”.

How is this actually used with bot data? It is very useful to break bot attributes into “weapon preferences” and “difficulty levels”. For example, here are some example templates for difficulty levels:

Template Expert
Skill = 90
Aggression = 90
ReactionTime = 0.2
Difficulty = EXPERT

Template Hard
Skill = 75
Aggression = 75
ReactionTime = 0.25
Difficulty = HARD

Template Normal
Skill = 50
Aggression = 50
ReactionTime = 0.4
AttackDelay = 0.7
Difficulty = NORMAL

Template Easy
Skill = 0
Aggression = 20
ReactionTime = 0.5
AttackDelay = 1.5
Difficulty = EASY

… and here are some templates defining weapon preferences:

Template Rifle
WeaponPreference = m4a1
WeaponPreference = ak47
WeaponPreference = famas
WeaponPreference = galil
WeaponPreference = mp5

Template Sniper
WeaponPreference = awp
WeaponPreference = sg550
WeaponPreference = g3sg1
WeaponPreference = scout
WeaponPreference = famas
WeaponPreference = galil
WeaponPreference = mp5

Template Shotgun
WeaponPreference = xm1014
WeaponPreference = m3
WeaponPreference = famas
WeaponPreference = galil
WeaponPreference = mp5

Template Shield
WeaponPreference = shield
WeaponPreference = m4a1 // in case shield is disallowed
WeaponPreference = ak47
WeaponPreference = famas
WeaponPreference = galil
WeaponPreference = mp5

Template Spray
WeaponPreference = p90
WeaponPreference = tmp
WeaponPreference = mac10
WeaponPreference = mp5

These templates allow the easy creation of a bot named “John” who likes to use rifles and is a pretty hard opponent:

Hard+Rifle John
Skin = 3
VoicePitch = 97

Creating a bot named “Fred” who also likes rifles, but is a complete newbie, is just as simple:

Easy+Rifle Fred
Skin = 2
VoicePitch = 110

By mixing and matching templates, a large number of bots can be created quickly. This arrangement also facilitates “tuning” bot behaviors - if “hard” bots are too hard, the values can be changed in just one place (the “Hard” template), and all hard bots will be updated as a result.

Modularizing bot personality data in this way keeps a large amount of data organized and manageable.
Distributing Mission Packs
The simplest way to distribute your Mission Pack is to zip up all of your custom assets (maps, user interface graphics, player models, your mission pack folder, and so on) into a single zip file, retaining the required folder structure. This zip file can then be shared with other CZ players, who can unzip the file in their main game folder, start the game, and select your mission from the dropdown menu.

For example, could contain the following:

czero\gfx\thumbnails\maps_wide\ cs_newmap_cz1.tga
czero\gfx\thumbnails\maps_wide\ cs_newmap_cz2.tga
czero\gfx\thumbnails\maps_wide\ cs_newmap_cz2.tga

kill vip looks broken to me. it works reversed as you need to get kill as vip instead of killing vip

i find an file inside of czero game files. at the manual an rtf file which says czmissiondoc

Which is same with this guide. i recommded using rtf file if your internet suddenly cuts and need to look at this guide. well. its just same

I double checked everything and even rewrote it. Are there any limits on how many Tour of Duties you can have because I only have one in the files as a test run.
GGwpAiushtha  [author] Jan 12, 2020 @ 1:15am 
Maybe error in some files? :lunar2019deadpanpig:
Littleozzz10 Jan 11, 2020 @ 12:11pm 
Hi, I was trying to make my own mission pack, but for some reason the game is using the default Tour of Duty missions and challenged. The game still sees my mission pack and everything in the overview file, but nothing in the career game files. Is there anything you could think of that would fix this?
sopar Sep 1, 2019 @ 9:31am 
i created an mission pack.
KnightBob7 Jun 13, 2019 @ 4:30am 
The problem with using numbers in bots names if your using it on the select character screen, but it has no problems in the regular BotProfile for non-mission pack play.
KnightBob7 Jun 13, 2019 @ 4:29am 
Hey, there's a problem with numbers not being registered in the custom names I give to my bots.
Is it fixable(as in making it include numbers and symbols) or no? Also there is a 10 letter limit to how much letters your bots will have when your picking them because of limitations I guess.
