The sensei is hard cause Veradux is mentally insufficient to attack...He never attacked once during the whole thing, and he died in like 3 rounds. I died in about 7 because all my moves keep missing. D=
Oh, and all the people asking about how to get to the corrupter, it tells you how to get the lgendary achievment when you press the trophy at the botton of the screen =D
Maybe instead of killing the gaurds, you can knock them out for like 10 sec, and if another gaurd sees it, it raises the alarm. And I agree with TrierMusic...Some decoys or traps would be nice
lol I got the achievment in like 10 min(When you get 125 kills so you max all your stuff, the rocket is your best friend...even better than a maxed shotgun! =D)
