yes, i have xfire, halo pc and ce: i would recommend to everyone who is making anything from Halo 1 or even some bits of Halo 2 (though its all amateur non-bungie maps) to dl Halo CE and buy Halo pc, which probably should be only about 15 of your crazy monetary units, maximum. Its really useful for source material for the detailing especially with the debug camera and the cheat_bump_possession.
