Sadly it wasn't a specific area it was basically they entire game it was able to work but is very rare for a example at the first checkpoint where you need to turn on the power after about 50 attempts the furthest i was able to get was the door that opens via a explosion and freezing after loading was finished aside from freezing alot I found no other problems with the games I have managed to beat it once but it took a few hours because of freezing and repeatedly trying for it to work I think the game is solid so far aside from that
