Warthog jumping

The Warthog Jump was first recorded by Randall Glass. It is commonly done in Silent Cartographer (Level), where you launch a Warthog into the air using grenades and/or rockets. In Halo 2, the Sputnik Skull can be used to make Warthogs fly farther than they would normally.

What Randall Glass Says

Randall Glass had a way to describe 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 the flipped warthog won't go off. Also, multiplayer grenades won't work either. Please try things before you ask.

Warthog Jumping on Zanzibar
On the beach on Zanzibar there is a ramp-like piece of debris (the ideal game type to try this is on Assault, although it will work on any game type), take the bomb and crouch walk at the bottom of the debris while looking just ahead of your own feet, this may take a few tries. Another player will need to drive the hog back a bit and then gain a lot of speed in order to ram you (the bomb carrier). You will be propelled the length of Zanzibar and land on the roof of the base. Remain crouching or you will show up on the motion detector. Be aware of the fan: it is quite easy to smack into it and lose the advantage. If you make it onto the roof, wait for your team to covertly join you. From there you have the element of surprise and should be able to gain the upper hand as there is actually a hole in the roof through which your bomb carrier can enter the base through.

This can also be done with Capture the Flag or Assault on Coagulation using the rocks where the Shotgun can be found. This is less risky if the person in the Warthog has the highest level of handicap on as they will do less damage to the player being rammed.
