Gears Of War: Surviving Sera

You are a survivor of the war torn and broken world of Sera, the world has been ravaged by the Locust War and The Lambent Pandemic but after the activation of the Imulsion countermeasure the Lambent has been destroyed and the surviving Locust have fled. The COG have begun their rebuilding efforts but have run into a few issues with uniting the world under its banner, COG Deserters and Stranded resist at every turns, making it harder for the COG to unite the world. But survival is the main goal in this harsh world. Based on the Gears of War games which were made by Epic Games, based after the 3rd Gears of War game. It's my own spin using the Gears of War universe but if the Imulsion countermeasure didn't destroy the Locust.
