So ... Privates is a game about tiny marines invading the human body. More specifically, it's about invading the private parts of the human body. We've seen screens before, but now you can see it in motion thanks to the magic of video. Suffice it to say that the game, much like anatomy itself, looks kind of gross and silly.
Frankly, we can see why it might have trouble passing peer review on Xbox Live Indie Games. At least the PC version is still comin... er ... will still be released.
