Just gonna say it.... this game blllllllooooowwwwssssssss....... it seems to me it is in the best interest of the player to suck at it... that way you have too kill more things and you get 1) a higher score... 2) More experience.... Having mastered the rush I am finding it hard to have enough XP to upgrade my skills.... So I'll probably have to go back and turn down the awesome just to get some XP...
