Hidden gargoyle

The Hidden Gargoyle is a Halo 2 glitch that can be performed only on the multiplayer map, Backwash.

Description
To find a hidden gargoyle in the Halo 2 map Backwash go to the blue base and go under the bridge. While you face the big Foreunner structure, look to your right and find the lowest plant with a green tip. Crouch jump onto it, then face the bridge above the ground. Do not jump on the bridge. There is a invisible barrier there. What you have to do is to find a smaller platform extending out from the bridge (when you get on the plant, face the bridge and look right), jump onto it and then go up it until it starts going slightly vertical. Then jump onto the other side to another extending platform on the other side then go up it till the platform ends. Then you should be facing a small corner in the tower with a gargoyle in it. You can jump into the gargoyle but you will just go through it. This spot is also a great sniping spot due to the wall you can hide behind.
