Right, I've finally completed the campaign and I can honestly say...... It kicks ASS. 
  
The gameplay is great, the story is excellent (and been approved by Hasbro to be part of the official canon), the boss fights are alot of fun (if somewhat tedious at times), the soundtrack is awesome, the sound effects are just as good and its the first game that has made me want to sit and watch the credits. 
 
Multiplayer: 3 player co-op is great in campaign mode and can help alot with the harder parts of the levels (although i dont understand why they didnt just make it 4 player), Escalation mode is fun to play, especially with 4 friends although there couldve been a bit more variation in the maps, Online is great with a decent choice in game modes, maps, character customisation, leveling up, challenge system and (although i haven't tried it yet) prime mode. 
 
Final verdict: 8-8.5/10
