E-Day stands for Emergence Day — the name given to the day the Locust Horde first emerged from beneath the planet of Sera in the Gears of War universe. It is the single most important date in the series' history: within hours, billions of humans were dead and the Locust War had begun.
Gears of War: E-Day (2026) is a prequel set on and around that exact day, 14 years before the original Gears of War (2006). You play a young Marcus Fenix fighting alongside Dom Santiago as the world collapses.
The Locust are a subterranean species. On Emergence Day they emerged from underground — through the ground itself, tunnels, and city sewers — in a coordinated, planet-wide assault. That act of emergence is where the name comes from.
In-universe, the COG (Coalition of Ordered Governments) initially reported it as a seismic event. When the true nature became clear, the day was given the formal name Emergence Day, soon shortened to E-Day.

The new game puts players in the middle of Emergence Day rather than years after it. It explores the origin story of Marcus Fenix, the start of his bond with Dom Santiago, and the first contact with the Locust — a perspective the original trilogy only ever told through flashback.
E-Day stands for Emergence Day, the day the Locust Horde emerged from underground and attacked humanity across the planet Sera.
Within the Gears of War timeline, Emergence Day (E-Day) is the date the Locust first surfaced — the setting for the 2026 prequel Gears of War: E-Day. The series dates it as the start of the Locust War, 14 years before the events of the 2006 original.
The Locust launched a simultaneous, planet-wide assault from underground. Billions of humans died in a single day, and the COG began a desperate evacuation and defense that led into the Locust War.
Yes. E-Day is simply the shortened form of Emergence Day used throughout the Gears of War universe.
