Phantom Flood whip

The Phantom Flood Whip is a glitch on Halo: CE. On any level with Flood Combat Forms, approach one until they start a melee attack. As the being swings back, shoot off the arm/whip it would use. Although the armwhip is gone, you can still be damaged as though it still there! This is a difficult trick to pull off, as the attack is usually quick, but with quick timing and good aim, you might be able to do it.
