Very good casual game

It saves your progress so you do not lose your work, and it is a moderatly difficlut stationary FPS. Once I bought the machine gun tower which helps by shooting zombies the game got way to easy. I have not finished it yet but I am %80 through it and it was a little bit of a let down when I bought it. other than that it is a fun quick shooting game. there are 40 or so levels and they go from 4-10 minutes at a time so perfect for "killing" time.
