Dead Purge Outbreak (WTF is this game,its so bad)

I know im shit at the game and i even played on easy,but i really dint want to try to do better because the game is bad and boring,its to much clunky,if they somehow fix that,and maybe add co-op or MP it might not be terrible like it is now (and i know i did not play the last 2 maps,i just wanted to stop playing,its basically the same map just changed night and day)
