Disappearing on The Covenant (Level)

The Disappearing on The Covenant (Level) glitch is a glitch on the Halo 3 level The Covenant that can make you disappear (though not being outside the map).

How to do it
After activating the second Tower, quickly run towards the Covenant Phantom. Kill one of the Elites using a Plasma Cannon and jump on it. After a while, the Phantom will fly away, and once it reaches a certain area, it will activate its Camouflage along with you. However, the Phantom will not move and will remain in that condition until you eject from it.

If you eject from the Phantom, you will experience a very slow fall which will be fatal once you reach the ocean. Your shields will also be knocked out.

This can also spark the 2 arbiters glitch. if you kill this phantom before the arbiter gets inside, he will enter the warthog if you pilot it. After killing the scarabs the same phantom will appear and drop off another arbiter
