Intense, classy, with historical accuracy, beautifull art, amazing gameplay.
It has everything a great FPS must have, plus some educational value.
The art is very well concieved, particulary the smoke, wich is amazingly gives a perfect sense of... smoke, like I've never seen before.
The sound, although, not it's highest point, it doesn't disappoint (voice acting at PDZ, anyone ?? YUK!!!), very funny to hear "Communisten!"; "Fascist!!".
The pace of game's great, and the difficulty raises steadly, and it's never frustrating nor lame easy.
People complain of multi-player, but it's not bad, but a game's core it's is solo part - MP is a must add-on, but for me the game rate is based on my relation, alone, with my pace, with my own sched - and in this dept. few games outstands this!
Very well done!
