Phantom Flood whip
From Halopedia, the Halo wiki
Template:Ratings The Phantom Flood Whip is a glitch on Halo: Combat Evolved. In order to see this glitch, you can go on any level with Flood Combat Forms. Play through the level until you see one, then approach until it starts a melee attack. As the arm swings back, shoot off the arm/whip it would use. Although the arm whip is gone, you can still be damaged as though it was still there. This is a difficult trick to pull off, as the attack is usually quick, but with quick timing and good aim, you will be able to do it.
