Movie Battles is a class-based, team-orientated Multiplayer Total Conversion for Star Wars Jedi Knight: Jedi Academy.
I was under the impression that this mod also had a single player mode, instead of only multiplayer. I've never been a fan of online gaming, but I admire all the work put into this mod. It wouldn't be fair to give a bad rating because I confused this with the Movie Duels II mod, though. It seems like it would be a good mod for those into online gaming, as long as people still play online!
