This is a difficult question to answer. Of course, in campaign, you can. The multiplayer on Halo: Combat Evolved, however, you cannot. Yet there is a game for the PC called Halo: Custom Edition, in which you can somewhat play against the computer. Some people have made maps with advanced AI that will attack you on sight. They are usually very fun, but they are also very complex and difficult to create.
Skull Haven I play Halo 1 though
Up to two players can play in the Co-Op Campaign mode on Halo: Combat Evolved.
I have halo one and ther is no way to play as a grunt its just single player as mastercheif and then multiplayer as a spartan. Maybe you can in halo 2 or so forth or maybe there is some kind of mod but no, you can't play as a grunt.
In Halo 1-3 you can play as him you dont have to do anything special to get him
if your talking about halo 2 or 3 no not legally anyway. for halo 1 though you "could" load an xbox emulator onto your ps3 and play it like that but most of the emulators for ps3 are quite buggy still.
Halo 1 is Halo CE.
Yes you can play Halo 1 on your Xbox 360
You can in HALO 1 if you use mods, but it has to be on the computer.
No, it has not released yet for the PC, only Halo 1 and 2 are for the computer as of 2009.
