Call of Duty’s distinguishing features, by and large, can’t be considered innovations–that’s too strong of a word. However, this is a game that pulls together many of the best aspects of other, similar games, and also includes all sorts of little “wish-list items” that may have crossed your mind while playing those other games. The result seems, above all, very well designed. The action in Call of Duty, ultimately, is arcadelike–much like in Allied Assault or Battlefield 1942. You can’t survive a shot to the head, but you can take a few bullets anywhere else and can keep going just fine.
