The best WW2 shooter i have ever played, the best FPS on the PlayStation, and one of the best on all platforms.
I remember spending long times with this game. The difficulty is above normal, and the controls are a bit hard. But once you get into it, you'll be amazed of the complex-ness of the game. Although you're on your own, there are bunch of nazis to kill. They are surprisingly intelligent. Their animation is top notch.
I liked that in a few missions, you can't instantly kill, you can pretend to be a nazi for a while by showing off your passport.
The gunfights were amazing. The only compliment I have is with the sniper. You can't see any further with the scope than you can see normally, because of the poor draw distance. Thus, it makes the scope (almost) completetly useless.
All in all, this game is a must try. I believe this game started the lavina of WW2 shooters.
I've had alot of fun with it, and I still wish that they made such brilliant games nowadays.
