[Official] Manual/Guide
By PAL-18
This is the official manual/guide for Modular Combat. In includes an indepth look at every element. Gameplay tips are also included at the end.

Modular Combat is a role-playing shooter based in the Half-Life universe.

The Resistance, Combine, and Aperture Science are testing the HEV Mark VI Combat System. Combatants face off against each other, and monsters, in the Controlled Combat Testing Facility, which is monitored by a super-computer known as BoSS.

There are dozens of modules that can be upgraded at any level, in any combination. Modules give combatants amazing abilities such as flying, teleporting, spawning minions, and shooting flechettes or energy balls. Basically, if you want to kill something in a special way...

We have a module for that.
To make it easier to read, several short terms are using throughout this guide. They are:

  • EXP: Experience Points
  • AUX: The battery that modules get their energy from.
  • DM: Deathmatch (No teams, its your vs everyone else.)
  • TDM or TeamDM: Team Deathmatch (Teams, its you and your team vs all other teams).
  • Free-For-All, FFA, PvPvM: Player vs Player vs Monster (No teams, its you vs all other players and monsters).
Modular Combat gameplay is fast paced and very chaotic. Combat difficulty is greatly influenced by the size and design of the current map as well as the skill of the other players.


When you kill other players or monsters, you gain EXP. When you gain enough EXP, you gain a level. Each time you gain a level you get 2 points (configurable by server host).

Each consecutive level requires more and more EXP to reach. The max level is currently level 25.

Kill Streaks
Kill streaks occur when any player kills a certain number of players in a row (without dying).

5 Kills: A message displays in the center of every players screen telling them about your kill streak and your player model begins to fade to red every few seconds (glow is visible when you are cloaked).

25 Kills: A message displays in the center of every players screen telling them about your kill streak, your player model begins to glow red (glow is visible when you are cloaked) AND all other players are put onto one team (they can't do damage to each other), they can only do damage to you!

Spawn Protection
When you first spawn (or respawn), you are temporarily invulnerable for a few seconds. When you fire your weapon, spawn protection is disabled. The default/max value is 5 seconds.
You will be unable to install Modular Combat if your Steam account does not own Half-Life 2.

Main Menu

Find Servers - Displays the server list. All official servers are prefixed with [Official] in their name.

Create Server - Starts a server. Use this if you want to play alone. If you want others to be able to connect, you will need to open several ports on your router/firewall. See "Addendum 1" of the Dedicated Server Howto. If you want to keep your server up even when you close your game, then you will need to run a dedicated server instead (click link mentioned in last sentence).

Options - Change your keybinds, mouse, Audio, Video, Voice and Multiplayer settings.

Quit - Closes Modular Combat.
Creating An Account on a Server
When you connect to a server for the first time, you will need to create an account. Your username can only contain English letters, numbers, hyphen and underscore. There is also no way to recover your password so make sure you write it down somewhere.

Creating a Suit on a Server
After you connect to a server and log in with your username and password, you can create a suit (up to 12) or use a suit you already created. Currently, your suits are locked to the server you created them on but we're trying to add universal suits that work on all servers.

You can choose a name for your suit (it appears on the scoreboard next to your name), a model and the team.

In team based game modes (PvM Coop, Team Deathmatch and Hoarder), being near your teammates gives you all a perk:

Players gain tactical advantage when near each other. This enhances weapon damage.

Players gain comradery when near each other. This gives them innate health regen.

Players gain energy boost when near each other. This gives them innate AUX regen.

Modular Combat uses standard source based controls for movement and firing plus new ones specific to the modification. Most modules can be set to a key, but because there are so many of them they are not pre-configured.

Suit Builds
This section was last updated April 11th, 2015

If there's a specific play style you want but you aren't sure which modules to buy, then here are some suit builds (with the minimum you need):

The Assassin
Evenly upgrade Recharge, Cloak and AUX Power Tank (in this order) until they're Level 10. Then put at least 1 point in Armor and Ammo Regen. Get HEALD too because it removes plague which can uncloak you.

You'll be spending most of your time setting up the perfect kill. This also has the added benefit of getting lots of kill streaks. When you enter a room you need to get as close to the walls as possible. Don't sprint as your AUX drain will be faster, walk at normal speed. If the room contains any unbreakable things like chairs, shelves, etc. jump on them. Players will not bump into you and you'll have a great place to attack from.
  • Recharge Level 10
  • AUX Power Tank Level 10
  • Cloak Level 10
  • Armor Regen Level 1
  • Ammo Regen Level 1
  • HEALD Level 1

Patient Zero
First max out plague to level 10, then evenly add points to Armor Capacity and Armor Regen until they're Level 10. Then put at least 1 point in Ammo Regen and Turrets. Get Teleport and HEALD to Level 5 (to remove enemy plague infection and heal yourself quickly).

Your aim is to stay as alive as long as possible and hide. When a player is near you and you have no chance of beating them, use your teleport to get away. Turrets also help defend you when you can't find a good spot to hide in (choose a dead end hallway or room, put 1 turret in front of the door and another in the corner of the room).
  • Plague Level 10
  • Armor Capacity Level 10
  • Armor Regen Level 10
  • Ammo Regen Level 1
  • Turrets Level 1
  • Teleport
  • HEALD Level 5

The Trapper
Evenly upgrade Turrets, Lasers, and MagMine. Certain Minions (Vort for instance) are good too, but you may want Recharge to offset their Aux drain.

Set the MagMine where it has easy access to draw attention and pull players and monsters in. Set up turrets where they can see the mag mine and shoot players or monsters that get pulled in, but not too far away that they can't shoot very accurately. Behind a fence is good because an Antlion can't shoot it, and monsters have to run around the fence to melee the turret.
Set up the lasers so they are lined up over the mag mine, as they damage any enemy that moves through them.
  • MagMine Level 10
  • Turrets Level 10
  • Lasers Level 10
  • Vortigaunt Level 10

Optional essentials:
  • Recharge Level 5
  • Armor Regen Level 3
  • Heald Level 1
  • Ammo Regen Level 1

Munster (Highly Mobile Damage-Dealing Tank)
Get Long Jump first, then evenly the rest of the modules in this list, saving Cloak for last.

When you have gotten used to the suit, adding cloak changes the whole dynamic of the suit from "Leap kill leap kill fly leap kill" to "Leap kill leap kill fly leap cloak snipe" or even "Leap kill leap kill leap around corner cloak ambush pursuers".
  • Long Jump Level 4
  • Jetpack Level 4
  • Cloak Level 4
  • Aux Recharge Level 10
  • Armor Capacity Level 10
  • Impact Level 5
  • Ammo Regen Level 4
  • Aux Power Tank Level 4
  • Armor Regen Level 3
  • Heald Level 2

Weapons of Mass Irritation
Leap all over the place while plaguing on and off to soften the players. Ignite them and blow them up if they don't burn first. Use freeze grenade when you have a shotgun and can't slow a player down to get a bead on them, as you can blow them away as soon as they unfreeze. Find someplace high up like a ceiling where you can rain down ice, fire and bombs on your enemies.

  • Recharge Level 10
  • Long Jump
  • Incendiary Grenade Level 10
  • MIRV Level 6
  • Freeze Bomb Level 3
  • Armor Regen Level 3
  • Plague Level 2
  • Clip Size Level 2
  • Ammo Regen Level 2

WARNING! Carry on reading! Or you will die, even if you only looked at the word warning! Once there was a little boy called Joey, he was ten-years-old and he lived in a mental hospital because he posted a shitty copypasta onto a People Playground mods comment section. He got so bad he went to kill all the staff in the hospital so the Feds decided that best idea was to get rid of him so they set up a special room to kill him, as inhumane as possible. And he sat there in agony for hours until he died. Now every week on the day of his death he returns to the person that reads this letter, on a monday night at 12:00 a.m. He creeps into your room and kills you slowly, by pegging you and watching you bleed to death. Now send this to ten other profiles on this one site, and he will haunt someone else who doesn't. This isn't fake. apparently if u copy and paste this to ten comments in the next ten minutes nothing will happen
