Gears of War 4

Gears of War 4 takes place 25 years after the events of Gears of War 3. Although the use of the Imulsion Countermeasure weapon destroyed all Imulsion on the planet Sera, killing the Locust and the Lambent in the process, the weapon forced humanity to adapt to new ways of survival after knocking out the use of fossil fuels, and bringing across the planet powerful windstorms called "Windflares". To protect the surviving human population from decline, estimated to be hundreds of thousands, the reformed Coalition of Ordered Governments (COG) established walled-off cities to protect its citizens from the dangers outside, while declaring martial law to prevent any travel outside the cities. However, some human survivors rejected the viewpoints of the COG and formed a group called the "Outsiders" that live outside of the COG jurisdiction, conducting raids on COG territory to gather resources.
