The Gears of War series of video games are mainly third-person shooters that have the player battling through waves of a brutal enemy known as the Locust Swarm. Even in spin-off games, like Gears: Tactics, The Locust is the primary threat. In the far future, humans are waging war on an Earth-like planet called Sera. In an effort to prevent extinction, the humans try to create a race of super soldiers, but this attempt fails and leads to the creation of The Locust Horde instead.
