When it comes to first person shooters, Call of Duty quickly climbed the ranks as one of the greatest. The realistic physics of gunplay along with edge-of-your-seat storytelling kept this franchise alive for so long. The franchise's multiplayer element has attracted an FPS community so committed that they could form their own city. When Call of Duty broke off into its Modern Warfare and Black Ops branches, players were treated to some of the most advanced, real-life weaponry seen in video games. On the other side of the spectrum, the wildly popular "Zombie Mode" took a break from the simulated war put gamers up against endless, undead Nazis. This feature soon became a classic and highly anticipated for the Black Ops II sequel.
