Dead and Reborn of amuse!!
This game is so addictive, not only for all fans of 'Katekyo Hitman Reborn' series , also for the lovers of fighting games.
Unlike the previous version, this new release has the following improvements: 8 new characters for the Future Arc series, including Byakuran, Dino and 10th Xanxus, 1 additional Special Move for each character, improvement on graphics and a lot of new stage.
Katekyo Hitman Reborn Battle Arena 2 is the game that don't kill you of boredom else of fun.

Definitely worth it.
It's a great game, with excellent gameplay, and more characters than the first one, which IMO was it's biggest flaw.
If you like the series, this is a must have.
If you don't, well, it won't be as good, but it's still a fun game.
