Halo Easter Egg - Rex

Like the Megg, only easier to find:

1) Start The Maw on any difficulty.

2) Play until you're in the Warthog-race thing ("Warning: Hitchhikers may be Escaped Convicts").

3) Play until Cortana says "Up ahead there's a gap. At top speed, we should be able to clear it!"

4) You'll do that huge fall and more than likely land on your tailpipe. Never worry. Take your warthog to the corner of the ramp that leads to the rest of the level. Position the 'hog so that you can climb on top of it and reach the top. Then do that.

5) There are two random hallways here. Go into the one on the left. Turn on your flashlight and read the "writing on the wall".

6) For those of you who are too lazy to check it out for yourself, it's the word "REX" painted in blood. This refers to the level's designer.
