Warthog Jump

Summary

The Warthog Jump was inspired by Randall Glass. It is commonly done in the Silent Cartographer Level, where you launch a Warthog into the air using grenades. In Halo 2, the Sputnik Skull can be used to make Warthog Jumps bigger than they would otherwise be.

How To Do It

What Randall Glass Says

Randall Glass had a way to say it.

Q: How did you get all of those grenades?
A: You have to shoot some soldiers. Shoot 5 of your guys (dropping
about 8 grenades total). They usually drop grenades when they die
(0-2). Here's a hint, trigger a Checkpoint before you do anything
(like shooting your guys). Revert to Saved if they drop nothing. 
Other people have discovered an easy method using CO-OP mode. You
and your buddy carry 4 grenades at the beginning of the level. Melee
each other from behind and you'll drop them.

NOTE: only dropped grenades will chain-react. The ones you find near 
he flipped warthog won't go off. Also, multiplayer grenades won't
work either. Please try things before you ask.
