Not bad at all
Story : Nice, nothing to complain about. 8/10
Graphics : Not bad, not perfect, but i've seen worst. Just a little thing about them.. I would have prefered human opponents than these strange blue things.. 8/10
Gameplay : Classic, but not very easy to handle in some situations (for exemple, to heal and keep fighting at the same time). 6/10
Sound : Simply perfect. Love the epic music, the cruel laugh, very enjoyable soundtrack. 9.5/10
Other things : The upgrade system can be more exploited, and it's a shame that we have to pay money for some items, but I can't understand it after all.
Average : 7.5/10 A fun game to kill time.. and people. :)
