Don't be misled by poor reviews for this game - it's a hidden gem with that old-school hardcore feel to it!
It can be played as either a button basher or a skillful game, the former leading to many a beating being received so I opted for the latter. If you do give it a chance you'll find you start to develop a rhythm during matches and with the quirky graphics and characters it can be a real blast.
So for those looking for a bit of fun and a worthwhile challenge I'd definitely recommend Facebreaker - if you found yourself complaining about Fight Night Round 3 being too easy you're in for a treat and old school gamers will welcome the return of those seemingly-impossible-but-when-you-work-it-out-you-look-uber-cool games of old :)
