If you are feeling suicidal today, just pick up a spartan laser or rocket launcher and aim at the ground. You could also do this with four shots from a brute shot. Or if you want to get creative, shoot a couple fusion coils or plasma batteries. Anything that blows up can kill you in Halo 3.
You press both bumpers, the left control stick, down on the d-pad, then press a. After the jump your gun should be down.
any where if you are close
You can't only on halo 2 and 3 you can
This can only be done in Halo 3 by holding LB, RB, Down on the D-pad, A and clicking down on the left stick for a few seconds in a non-live game.
There really isn't Halo 3 cheats except for manually done cheats from the controller itself. This cheat is a way of holding down your gun like master chief in one of the Halo 3 posters. If talking about like " type in this cheat and you unlock all the maps cheat" well no. There are no cheats like that for Halo 3. :)
nope sorry
no
i dont belive that you can in halo 3 i think it was exclusive only to halo 2.
Plasma Pistol, as it is in about all Halo games.
no
its not a gun but the energy sword
The 3 round burst gun from halo3.
there is no codes in halo 3 ... -.-
there is no such thing
