I didn't play WIMP mode
I am a big fan of zombies and this was just great to play because it was just zombie after zombie after zombie! The graphics were fantastic and I liked the design of my ship, or whatever it was. Every level just seemed to go on forever with the powerups and everything, which makes it addicting. My favorite would probably have to be the grenade. It's so fun watching those little guys go on fire and have all their ghosts come on there at once. My tip for players who are having trouble is to really spread out and keep moving as you are firing.
