I almost got screwed at the end because I was charging my ps3 and the wire move and for my controller wasn't responding. Luckily it didn't kill me but had he, I would have definitely had rage quitted..
This was the place I was stuck at for days.. Probably the 2nd longest. You could tell how happy I was after I made progress. When I got past this, I actually believed that I could finish this game in chaos mode.
