The Gears of War series takes place on Sera, a fictional Earth-like planet. The series puts emphasis on cover-based combat, in which players can use objects to avoid gunfire or safely engage enemies. In January 2014, Microsoft acquired rights to the franchise from Epic Games. The first installment of the series was released on November 7, 2006, for the Xbox 360. The fourth installment in the main series is set 25 years after the first title, and is set to be released in September 2019.
