I've had a few glitches myself on the PS3.
I've had the menu lock up.
I had the game crash behind a loading screen once.
I had the weird physics screw up where instead of landing after a jump I'd be floating 3 feet off the ground neo style.
I've had an audio log play everytime I load up the game.
I've had utterly random ragdolling happen upon jumping, which I admittedly found amusing.
In co-op my friend has glitched out while jumping so bad that he'd go up, but not come back down, to fix this I had to get a vehicle, fly it directly under him, then have him get in and back out.
I've also had a bizarre glitch in which my characters walking animation switches, I play a female character, and sometimes, usualy after a cutscene, her walking animation switches to the male characters. This requires either getting in and out of the mech suit to fix, or reloading my game.
None of these have been game breakers for me, just slightly annoying or amusing. Hopefully they get patched.
