FlagRaiders may be described as a "single player capture the flag" mod, designed for Quake 3 Arena: you can play it all alone, without the need of other players (but if you want, you can play it in multiplayer mode, too). You have to grab a flag and carry it along a difficult path, avoiding deadly traps and passing over obstacles. It requires control skills, using techiques as strafe jumps, rocket jumps and plasma climbs. It uses "Vanilla Q3" game physics.
