UTMCoop is a small mod for the classic Unreal Tournament. If you are familiar with Unreal 1 (Or have played the Monster Hunt gamemode), then you'll definitely like this, because this mod lets you be one of them monsters!
Me and my friend, again. Doing a Skaarj Sniper vs Skaarj Infantry on Agony, it was hilarious. Recorded with FRAPS on my own server.
