Well, that #2 game disc of MASS EFFECT was the demise of my ps3 game unit as it would seize up game play about middle /halfway thru saying corrupted data unsupported or some kinda' B.S. like that, so I played the 3rd game disc(it ended in a pretty cheesy fashion) but felt deprived of my full gaming experience & ran the #2 game disc again, well it vapor locked in about the same area of play,up to the point where it would just continually attempt to reboot after clearing the corrupted data& restart ,it would stop at 48% and sit there for 15-20 minutes, then rocket shoot to 100%,,& run the same problem thing up on the screen.
