Ratchet and Clank: Size Matters Glitches
This one is pretty cool. What you need to do is go to challax and in either the fist or the second area (Im not sure which) there should be a part of the wall where it looks like you can run up it with the gravity boots but you cant. When you get there attemt to ren up the middle of the section of the wall and you should just kinda hover there and watch ratchet for a while and you should see his armor slowly lift off his body!!!
