They aren't the same as 1, no random spawns which include 100's based on your partner standing on specific spots of maps, no nade weapons from across the mapp, grenades nerfed, no 3 shot TSK, sniper auto aim introduced, inability to time weapons and powerups for ultimate map maneuverability.

@My Spot who tried to explain to me Halo CE had be done before on PC in a variety of other games, and I just couldn't do it man. IF you didn't play Halo CE in 2002 through internet programs pretending to system link xboxs I can't help these guys understand the most advanced shooter of all time.
I say this as a CS early 2002 guy too and a Quake 2 guy.
