Flying Raptor Glitch:

First, find a map with water in it that you can submerge in. For this 

glitch to work you must be a Raptor (you can choose either raptor you 

want,it won't matter). Find the body of water in the map and jump in 

it in 1st PERSON. Once you've submerged into the water, press X to 

switch the camera to 3rd PERSON. Hold A as if you're still swimming 

and *drum role* YOUR FLYING!!! You can now go anywhere on the map by 

just walking. If you want to go back on the ground ( and still want 

to live), simply switch into 1st PERSON ( press X ) and try your best 

to land back in water (instant death if you don't). Note: You are flying

because the game still thinks your in the water, that means you can be

drowned. You should get at least 2 Regen Power Ups ( the

purple looking clam you find throughout the map ).
