YAWN!
I maybe being a little harsh, but all it is is hold down the win button and spin in a circle...
The Maps are dull, the music is way over excited, and after a cople of minutes, a bug apeared where the ombies just stand and wait to be attacked one by one, removing any difficulty that there maybe from running around in circles firing.
More detailed maps, better weapons (visual effect etc) and shinyer animation because the enemies looked like slugs...
Fun, for a few seconds
