Grenade sniping

Description
Grenade Sniping is a trick that requires precise and flawless accuracy done in Halo: Combat Evolved. Have the Infinite Grenades option turned on and choose a multi-player map like Longest and climb up a ladder to a ledge. Then, keep throwing grenades everywhere continuously. This makes you a hard target to get to, unless another player has a Sniper Rifle or another long range weapon.
