Well, my game is just plain screwed up. Everything runs perfectly. Menus are looking normal and the game.... wait not that one. Yes, I tried to play one deathmatch and the colors we're just screwed up. Worms, weapons, land, everything. I print screened it but it doesn't really show the worms, just landscape for some reason. Here ya go:
