Me and my friend are making an Aliens vs. Predator vs. Humans mod, and need to know if theres any way you can have them take the team colors off, and have your players default colors show as they would in deathmatch, but as a team game. Any help would be appreciated, so thanks in advance!

In the config.exe in the soldat folder, check off clanmatch in the "extras" tab.

Nope. Team colors are there for a good reason. Without team colors, you won't know who's who.
