Great visuals, fun gameplay, clever title, and a unique take on tower defense. I liked the new enemy reveal screens. I did encounter 2 small issues with 1 gameplay issue, first, on a widescreen most of the UI goes off the screen, but I was able to change my resolution down to 1920x1080, and second, once I got to the last 60ish seconds, the game was running at about 4 fps, but that might be because I had 20 3 stack grenade launchers. Then the issue with gameplay isn't that important, but I felt that I wasn't able to use the robots close/far/strong/etc. due to the fact that I would have to set it for each individual gun (unless I missed something that allowed multi-editing), and I didn't really want to have to manually set 60 guns, while also being attacked by the undead. Other than those 3 things, it was a really great game!
