Elevator glitch

The Elevator glitch is a Halo 3 and Halo 3: ODST glitch that allows players, with a partner, to get to very high places. This can be done in Matchmaking, Custom Games, Forge, and Campaign, as long as you have a right angle.

Walkthrough

 * 1) Find a partner and a 90 degree corner that extends upwards higher than around six normal jumps.
 * 2) One person should go and look directly into the corner, than walk straight into it.
 * 3) The partner should crouch on the first person's head and do the same.
 * 4) The person on the bottom should start pressing A in a rapid, repetitive way, making sure that both people are looking into the corner and walking into it the entire time.
 * 5) If done right, you will go up until you reach the top, and your partner will be in the, supposedly, "unreachable" spot.
