Drop Dead on The Great Journey

The Drop Dead on The Great Journey is a glitch in Halo 2 that makes the Arbiter drop dead.

Walkthrough
To do this glitch, go to the bottom floor of the Control Room when fighting Tartarus. If you crouch down, the Arbiter will drop dead. This is because when you crouch down, you touch the kill barrier that keeps players out of areas with Invisible Walls.
