Imperialist, I tried it with any character and it worked. All you do is climb the wall in biped, and you're there! Also, what is cool is that from there you can walk across the wall without falling. And another glitch in Alinos Gateway is with Spire. You know the spot where there is a huge waterfall of lava in the back? from facing that, turn left until you reach a huge rock in your path. Go around it and walk in between the stone and the huge pointed rock. Go into alt while turning left, and you will be in the wall. Also, if you need the imperialist, you can roll up the wall while still in the boulder and not be seen. The glitch in combat hall that hornuale000 is talking about is with any character. Choose one, and go to the corner walls on any side of the hall. Charge up your missiles, then, while holding back and left/right, depending on which side your on, shoot the missile at around a 40 degree angle. You will fly through the wall, and.....tada! You're invincible! This takes a while to do , so take your time. NOTE: I do not use these in Wi-Fi and neither should you. They are just for fun and I use them just to impress my friends.
Hope this helped!
