Gears of War: E-Day is a prequel set on the planet Sera, 14 years before the original Gears of War. Marcus Fenix and Dominic Santiago, joined by new Bravo Squad members Mags Carter and Lucas Reyes, fight through the industrial city of Kalona over the three days of Emergence Day, when the Locust Horde first erupts from underground.
Developed by The Coalition with People Can Fly on Unreal Engine 5, it keeps the series' cover-based third-person combat with a reworked movement system, destructible environments and the returning Active Reload. The campaign supports four-player online co-op and two-player split-screen, alongside 4v4 competitive multiplayer and Horde Siege, a co-op mode for up to 12 players in three squads.
