Scarab boarding glitch

The Wraith Boost Boarding Glitch is a glitch that can be performed on the Halo 3 Campaign level The Storm. The glitch allows players to board the Scarab earlier.

Walkthrough
Start the level from the beginning. When you get to the area with the Anti-Air Wraith, kill all enemies except the Anti-Air Wraith driver. Melee off the side "wings" off the Wraith, and hijack it. Drive the Wraith into the next area and kill all enemies. When you see "Judgment" appear on the screen, save and quit. Then, resume the mission.

After this point, do not save and quit. Position the Anti-Air Wraith at the spot where the Troop Transport Warthog was. When the Scarab's leg comes down on your position, press LT to boost; the Wraith should be sent into the air. Then, exit the Wraith and you should be on the Scarab's deck.

This may take a couple of tries, and the Wraith's position is a significant factor; if your position does not get you on top, press the Xbox Guide button and sign out. You should start where you last saved and quit. Sometimes, this glitch might overload the map, often causing the Hornets and Pelican to vanish, and sometimes even eliminating the Scarab and other objects.
