I love first petson shooters and am a fan of Doom. So this left me just a little let down. The good: Action packed, manic, great graphics and gore! The bad: I found some bits ROCK hard even on easy level, frustratingly so. Maybe I'm getting too old and slow! The ugly: The jumping and grabbing...eurgh. Again, very frustrating. I do not want monkey bars, grabs, ledges or climbing walls. They slow the game down and lets be honest, this isn't a platform game. All the jumping and grabbing feels a little off. And just when you think you've finally sorted the most fiendish grab, jump, zoom and grab along creeps another section :-( So overall very good just leave the jumping and grabbing to Mario or Mirrors Edge games.
