alright...theres a glitch that supposedly lets you "walk through walls"
to do this use the combo X Y Y then sheild immediatly afterwards...all this did for me was send me flyin through the #@%$ floor

any1 else have problems with this "glitch"
if u did post here

It's a gamble, you have to use specific timing. Too late you go under the wall. Right time, you go through the wall, simple as that.

Speaking of glitches..I had had one of those Red Bee enemies glitch into the floor on me at one of the Shamar night stages. Needless to say I had to restart from my current checkpoint because I couldn't kill the enemy, and was trapped in one of those "arenas".
