No game is perfect, but this one comes close.
Only down side is you can't do team battles.
Other than that, the costumes are a great idea, the specials are as good as they get, classic Bomberman fun and lots of new stuff too. Different views and improved graphics.
Playing online is what it's all about so I will forgive the lack of a single player campaign (it wouldn't have been fun anyways).
Up to 8 players on live, 4 on one console and another 4 online. It's every man for himself.
So as I said, no teams, making it kinda suck when you want to be a team with your friends and take down a team online. Still, a great game.
Only about 10 bucks, so it's really worth it.
Don't bother buying the add-ons cause all you get is some costumes (which are cool) but not cool enough and some lame modes. They really need to add team play if they want me to pay for another download on this game, but if you are a fan you can buy the 3 or so downloadable content options available.
