The best WWII single player experience since Medal Of Honor: Allied Assault. Better, really. Nothing really revolutionary, but it takes everything you ever liked about other WWII shooters (and a few things you wished had been in them) and puts them all together into a kickass game, complete with WWII movie references.
The multiplayer is the best since sliced bread. Well, okay, the best thing since DoD (Day of Defeat for the uninitiated). A definite must buy.
