It's a new game coming to Steam soon. Apparently Hitler also brought back Dinosaurs to fight for the SS. :eek:
The game doesn't look THAT great, but you do get to punch dinosaurs with your bare fists. And yes, there are dinosaurs with guns (which you can play as!). So that's pretty much awesome and worth a try on it's own.
Give the trailer a look, if for nothing else than a good laugh.
