a grunt.
It is impossible to play as a grunt in Halo: CE (aka. Halo 1) without modifying the game.
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.
No.You can only play as an elite.
Don't you know anything about halo? no! of course you can't play as a grunt! what do you think this is? national bush week? playing as a grunt... what kind of world would this be if you could play as a GRUNT? of all aliens, you ask about a grunt. n00bs, these days. they just get dumber and dumber.
It is impossible to play as a grunt in Halo 3, even when modifying the game. The only thing you can do is modify a film from campaign and make it look as if you were playing as a grunt. Even so, the typical user has absolutely no means of doing this unless they have connections in the modding scene and are willing to pay good money.

Sorry, I think you can't do this unless you mod halo 3.
