I'm going to save myself some typing by posting this link.

Seriously, it'll tell you more about the game than I can.

Back in part 12 of the original GameTrailers version, zuiop made a mention of the German version replacing all the humans with robots. You can find some footage of the German version here.

Also, go ahead and compare the front box art of the German version of the game box with that of the American/non-German versions. Notice how the blood from the dinosaur's claw swipe is removed...
