No Weapons Cheat:
While playing assault or capture the flag, switch your smg for a plasma pistol, the pistol now being your only gun. Charge up the pistol and don\'t shoot, while charged hold in X and walk over the bomb or flag, you will then exchange the pistol for the flag or bomb, then press your right trigger and you will be gun-less you now only have the ability to throw grenades, but watch out because the moment you walk over a gun you will pick it up!
Best I could find, idk if it works.
However, from what it says above, you can only throw grenades so apparently you can't punch, still, the stance would look good.
