Over the years, Call Of Duty has started to rely less and less on story-telling, and more and more on the unbelievably successful multiplayer elements of the games. Quickfire thrills are the backbone of the franchise, one which has moved with the times of gaming, and pulled in a remarkable fortune in the process. The latest release, Advanced Warfare, has maintained the illusion that all is rosy in the COD universe, but cracks are beginning to show in the formula. Even the best gaming series can only last so long - inevitably, the gaming public will tire of anything presented to them for any substantial length of time, regardless of how well done it is. Going back to 2007, the world was enraptured by Call Of Duty. Rising up from the shadows of other World War II-inspired first person shooters, such as Medal Of Honor, COD really hit home with Modern Warfare. Not only did the game have genre-defining multiplayer, but also featured a single-player experience which came highly recommended. For Modern Warfare 2, Infinity Ward wanted to up the production, and it's still a contentious point of conversation whether they nailed it or proved too ambitious with their multi-layered story. Leaving such arguments up to the gamers themselves, the developers have charged ahead with Call Of Duty, taking things in an altogether different direction. Many gamer's favourite part of MW2 lies not in the superb gameplay, nor the multiplayer action, but in the voice acting of Sergeant Foley, who is a true linchpin of the game. On the surface, Foley is just another typical army character, but Keith David adds such depth to even the most one-dimensional of figures. Creating humanity in any game character is an achievement, but especially so when there's not much substance to start with.
