...Fantastic...
Like in most reviews, I'll mention the good and bad parts.
Positive:
Great cast of characters, and unlockables.
Weapon Master mode (kind of story mode), where you can unlock characters, weapons, modes,...
Great gameplay, you won't be able to put down the controller.
Graphics that you won't see in many other games.
Clear sound and music, that fitts good with the fights.
Many modes.
Special guest character: Heihachi from Tekken.
Even if you unlock everything, you'll still want to play.
A lot of moves for every character.
Great depth with the 8-way run, vertical and horizontal slash.
Negative:
Some characters share a bit the same style.
Some weapon master levels are very hard.
In the end:
If you don't buy it you're just ST00PID, seriously, you won't be able to put it down..
