First of all: Good job!
There's things that can be improved, yes, but you're definitely on the right way!
Some things I'd work on:
-lights. I know you want it dark, and dark fits perfectly. Just make it a tiiiny bit lighter?...
-Some friends? Or more action... more NPCs... something that fills those empty streets. If I understand correctly, you're being searched for by the Nazis, and you're hiding from them. That means you're alone, and try to stay in dark, empty places. Fits perfectly. Still, there should be a bit more in those streets and houses. Cars (that don't need to be driving, just standing there) etc. But since you're still working on it you're probably just not there yet. Just thought I'd point it out anyways.
-The opponent models. Their animations, their skins, the models themselves. It just doesn't look quite right next to that great car model. Again, you're still working on it, it's not done yet. So that gives you every right to have those models in that game
-The camera does, i think, not move much when standing still. It should move around a little bit, because the player's panting, or breathing.
-Last thing: The player doesn't die fast enough. I'd make him have less health. Yes, he's the hero, but a realistic hero is, in my opinion, more fun to play. The guys shoot him about 20 times before he dies. You don't need 20 bullets to hit you before you die, 4 or 5 is easily enough. That way it would be more about hiding from the germans as well, you couldn't just run around in the open.
All in all: Keep it up! I like the atmosphere, the germans shouting around, the way you hide in the dark. The Opponent AI isn't quite perfect yet, but it seems to work very nice already.
