For another WWII FPS game that came out in the time where WWII FPS-es were coming out all over the place, the campaign is special because it followed a bunch of nobodies no one's ever heard of (mostly because they don't really exist) in this massive war, and did it well. I will forever remember it as one of the few games where you can blow off people's limbs in a satisfying fashion. The multiplayer was well executed in that all the newbies were packed together so you wouldn't have super-vet crushing someone who's never played the game before. You can also blow people's limbs off. Treyarch's then-revolutionary zombie mode blew my mind much like I blew zombie's heads off. This game is one of my favourites, and was an instant classic.
