A Parody better than most of the originals
Apparently a lot of reviewers haven't bothered to read the author's notes before spouting off at their pie-hole. They're bitching about how the game is too 'generic' and too 'samey', which is THE WHOLE POINT. It's called 'Generic Shooter' for crying out loud!
That said, it's a pretty spiffy game, with good graphics, a smooth interface, and a nice little twist with having to place the auto-turrets yourself.
