Diverse fighting styles, great graphics, and blood. Lots of blood.
The game play is incredible. Super smooth and fluid. Every animation looks crisp and clean. The special moves have defined the series its entire life, and without a doubt are awesome, especially Sub-Zero's ice attacks. Some moves are cheap, (Noob/Smoke's moves) but that's expected with any Mortal Kombat game. Online play is also very fun and intense, but has many special move-spammers.Trust me, just play against your friends or call a truce before the match... Play the story mode instead. You'll be entertained by the story and fights.
Overall, the game is highly addicting to anyone that appreciates a good fighter. With an assortment of cool characters,massive amounts of gore, and hot chicks, no self-respecting guy would turn it down.
