Exo arm cheats for Halo 3

Exo arm

Be in forge and have at least 2 people. The host must be Spatan/Elite and the other player must be oracle. Make a shotgun and both pick it up at the same time. The oracle has to hit RT to make his arm spin. Then the arm will rip off. The person without arms has to kill the other player. Then you should have an exo arm until you die. This may take a few tries or different guns.
