Unaware Survivors follows the story of a group of Gears who have become seperated from the rest of the surviving COG forces following the Sinking of Jacinto in 15 A.E. These Gears, led by Colonel Donald Berkeley, must fend for themselves against territorial Stranded, the crumbling remnants of the Locust Horde, and the terrifying new Lambent threat. Many of the cast members are carried over from War of Nightmares.
Though Unaware Survivors takes place within a much smaller time frame than War of Nightmares, both segments are intended to have roughly the same amount of content.
The Unaware Survivors segment of Gears of War: Dark Horse is overseen primarily by Lieutenant Davis, whom is also responsible for its creation.
