ill be honest , this game ia very boring, the shooting system is not good at all i think its the worest shooting game i ever played, gameplay is so bad and super quick, if you got 5 red cryatal and escape wich you can do in less than 5 minutes , you earn some xp, some points to get a higher rank and thats it.
i liked the zombies alot it was the only thing that well made.
thanks
