It's a mad combo fest!
There are a few game modes, from the classic arcade stile when a tag three vs three match happens and you have the ability to switch in between your characters any time you want. For a single player, this is where you probably be spending most of you time. The other mode is the mission, with consist on you learning and performing the moves that each character has, and it get's really challenging on the most advanced ones.
The online mode is pretty good, takes a little too long to find matches but they can be a lot of fun if you're good with the combos, which is not my case, so I have fun getting defeated by most people.
Overall, this is a great title for any fighting fan, from the amazing graphics to the cheesy lobby music from the menus, really a charm that this series is knows for. It's a must have for me.
