Nearly every game that falls within the genre of FPS ships with some version of an online component. To not do so usually means that, regardless of how good the single-player portion of the game may be, critics and players are going to pan the product because of this shortcoming. Games such as Rainbow Six: Vegas, Gears of War and the Call of Duty series are immensely popular among players. Call of Duty: Modern Warfare is still one of the most played games online, even two years after its release. Some games, such as Counter-Strike and Tribes, don't even bother with a single-player campaign, focusing instead upon the multiplayer mayhem of team Deathmatch (and other variations) of online FPS. Following this line of thought, Zipper Interactive is set to release Massive Action Game, commonly referred to as MAG, in January, 2010."
