All the traps to intentionally kill you. This is just painful to play and NOT fun. You can keep you stupid rewards. I am not playing through this crap on any difficulty level!!!!!! There was zero need to make this many ways to kill the player. I mean it is just idiotic that you would play this and think, wow a player may die a dozen or more times with electric false doors, so it is the funnest thing we have ever released!! Just frustrating. I have no interest in fighting my way through stupid traps just for an exotic. You can keep especially considering I may have to do this 4 or 5 more times are higher difficulty levels. Devs making bad decisions and if they thought this was fun and engaging. THEY FAILED!!!!!!!!
