Well there is a list a mile long of negatives but i'll start with the positives, the graphics are quite polished for a psp game and the stealth elements can be good fun but constant base infiltrations just get repetitive, there is a couple of flying missions to break up the repetitive gameplay but these are short lived and don't go on for very long, the boss fights can be good fun, unless you keep dying because of the impossible difficulty, which leads me onto the difficulty curve, easy is just right difficulty, normal is impossible and hard, well thats impossible. the camera in this game is extremely annoying so when hiding behind walls, all you can see is the inside of the wll, which makes some sections very hard, but what else do you expect from a film game, rushed and executed badly, one for hardcore James Cameron fans only.
