4.5 Great game, but... UtopiaX | 10/03/2009 | See all UtopiaX's reviews (20) It starts perfectly. Some easy missions to learn the controls and a interesting story. But then when you finished about 70% of the game it gets extremely difficult. It gets from quiet easy to very difficult just like that. What a learning curve?!? I played the game for about 80% but then just stopped. When you almost finish a level but then just die you have to start all over again. Some levels take about 40 minutes to finish so this is really irritating. Checkpoints wouldn't be bad.
