The following are required before you can start:
This guide is written on how to launch any version of The Armory theaters. So depending on which theater you have chosen, the command will vary somewhat. Either type or copy and paste the associated command for whichever theater you have chosen to want to play into console.
Select the theater you are wanting to play
After you have successfully inputted the proper console command for the theater override (mp_theater_override) and it did not error out, it is time to load up a map. In console again, type one of the following, replacing MAPNAME with the map you want:
Checkpoint - Example: map ministry_coop checkpoint
Conquer - Example: map ministry_coop conquer
When you have typed the map command, with the desired map name, click/key enter and the map should load.
For examples of the map names available by default with Insurgency, click here.
Once the map has loaded and you can confirm the theater has loaded properly -- one way of doing this is the character slots should consist of Weapon Sergeants and Weapon Specialists (a unique feature to these theater files.)
Control Allocated Supply Points
Open console (~) type mp_supply_token_base XX -- XX being the desired amount of supply points, then key/click enter, then again in console type "retry", map should reload with desired supply points.
