The following are glitches that work in multiplayer and sometimes adventure mode.
1.) Combat hall glitch. You've all heard of the one where you run in the corner and blast yourself right? This is similar. Walk up to the second floor of the level and go over the bridge to an area you need alt form to get through(the second area you reach is this one.) walk backwards into the tunnel as far as you can in biped form. While running backwards into the tunnel fire a fully charged missle so the balst barely touches you. You will be balsted into the area in biped form. (You must use weavel to do this.) then switch into alt form and the wall to your right is gone. Fall down through the wall and you will land in the hallway. But you can control this fall so you land in a black area where noone can hit you.
2.) Alinos gateway. This is a simple glitch. All you have to do is go to the area with the imperialist. Take the imperialist and go left towards a rock pillar/wall/thing and walk into it looking up. You will walk straight up the pillar!! Once your at the top of the pillar you can continue to scale the wall it's up against(very difficult) or you can stay on the pillar it's a great sniping point!
