Offline mode is very comprehensive, it is composed of several modes: arcade, ghost, versus (multi 2 players offline), fighting as a team (2 players), timed challenge, survival training and team of two (multi offline 4 players).
The mode "Fight Lab" is a scripted tutorial will help you learn the basics of gameplay.
You can choose different levels of difficulty, be careful even "Easy" will need to fight hard to win matches. Apparently an update to rebalance the level of difficulty in "Easy" mode will be available in October.
You can customize characters, picked up after each fight loans used to buy outfits or accessories to change the look of your fighter from head to toe.
The online mode is a classic fighting game, not surprisingly the level is very high .... you really have to train a lot to hope to shine.
Warning: you must install 7.5 GB of data on the hard drive of the PS3.
