Fantastic! A massive improvement from the original. Consisting of an above average single player mode and arguably the best multiplayer option currently on the Gamecube. The single player story mode includes stealth, humour and all out action. There are three different difficulty sections lasting you for a good amount of time. Also two other modes are available: Challenge and Arcade League. Both contain a series of goals and targets which when completed you are rated: Bronze, Silver, Gold or Platinum. The higher the medals the more unlockables become usable such as new characters, new multiplayer options and cheats. The thought of being able to play brand new sections and becoming an inch closer to 100 percenting the game makes you keep on trying and trying. But the fun really starts when playing the multiplayer. Once started you cannot put the controller down it is unbelievably addictive and extremely enjoyable. If i were to tell you every multiplayer option within this game i think it would cover about ten sides of A4. If you want to find out just buy it! I recommend it confidently unless you're insane.
