It seems like everyone and their mother plays Black Ops these days. (Seriously, our mom is on like ninth Prestige.) But Activision's formula of going all-in with a multiplayer FPS experience—packaged with a tacked-on single-player campaign—can be traced back to Battlefield 2 in 2005. Electronic Arts' version of "modern warfare" thrust you into the middle of a world war where you helped drive America (f#%& yeah!) and Europeans (not-so-f#%& yeah!) through the heart of the Middle East and China. The robust multiplayer offered squad-based combat, leaderboards/achievements, and support for up to 64 players. That's, like, a lot. And no Hardline Pro exploits!
