Read me :
Allies versus allies mod.
This mod changes the axis side to allies. Meaning, it's a civil war circa the WWII era. You can now have a howitzer war against each other. I have only tested this mod in a stand alone mode against AI player; which works without any glitch. Pretty sure it would work in a multiplayer LAN environment too. Why is it so small? Because all I did was change the race type in the Axis profile from "axis" to "alies". That's it !
As usual, just copy the AlliesXAllies folder and the AlliesXAllies.module file to your Company of Heroes folder. Then you need to amend the "Target" parameter in the property of your COH icon (best to work on a copy of the shortcut icon) to:
"[Drive:][Program Files folder]\THQ\Company of Heroes\RelicCOH.exe" -dev -modname AlliesXAllies
Double click this amended icon to play the AlliesXAllies mod.
Have a happy artillery day !
