We're having a Halo CE LAN tourney on the PCs in Uni on Wednesday.. Never played it on PC and haven't played it in years, what should I know? How do I force resolution and change FOV, and can I somehow use something to force player colours?

Got any little tips and tricks for actual gameplay, too? I know you can weapon switch and then melee to let you shoot quicker upon respawn, at least. Are spawns like Quake?
