This glitch works with any hunter. At the either end of the hall in combat hall, you can go through the walls with the pipes with a push of a missle.You start off by charging a missle. go to the end of the hall closer to the jump-pad. Run backwards on the pipe, staying close to the wall on your right.Still walking backwards, look down at a 45 degree angleand let go of the fire button. If done right, you should jump NorthEast and you will land on an invisble platform. If you dont want to fall to your doom, you should shoot around at the platform with a power beam to see how big the platform is.You can shoot people outside the glitch but they cant shoot you. You can do the same thing on the other side of the hall, but you have to jump NorthWest and the platform there is smaller. Watch out for Trace Abusers though, they can shoot through the walls in certain places with the Imperilast if you wanna know how to do that, check out Neoseeker.com.I forgot 1 thing you can only do the missle push glitch when you are playing a 2-player match or else there wont be any pipes.
