Gears of War: E-Day is a mainline origin story set fourteen years before the original Gears of War. It follows younger Marcus Fenix and Dominic Santiago as the Locust Horde emerges beneath the planet Sera and launches its first assault on humanity. “E-Day” means Emergence Day—the disaster that begins the Locust War. Xbox lists the game as released on October 6, 2026, for Xbox Series X|S and PC.

What does E-Day mean?

E-Day is short for Emergence Day. It marks the moment the Locust Horde erupts from beneath Sera and begins its devastating attack on humanity. The game focuses on the first days of that invasion, when people are caught by surprise and the Locust are still unfamiliar and frightening to those confronting them.

That point in the war makes the story different from one set amid an established conflict: the characters are facing the sudden beginning of a catastrophe, not simply another battle in a war they already understand. Xbox’s game description and a 2024 Xbox Wire interview with the developers frame it as a survival story during the invasion’s opening days.

When is the game set?

Xbox places Gears of War: E-Day fourteen years before the original Gears of War. The story follows younger versions of Marcus Fenix and Dominic Santiago at the beginning of the Locust assault, making the game an origin story for both the characters and the conflict that shapes the series.

Who are the characters?

Marcus Fenix and Dominic Santiago

Marcus and Dom are the central familiar faces. They are young soldiers trying to survive the invasion’s opening days. The developers have described the game as an origin story for the pair and for the bond that becomes central to the franchise.

Mags Carter and Lucas Reyes

The wider squad includes two additional playable characters, according to Xbox Wire’s 2026 interview with The Coalition:

Is E-Day a spin-off or a mainline Gears game?

It is a mainline entry set earlier in the series timeline, not a spin-off. The Coalition described it as an origin story that adds context to later Gears stories. Studio Brand Director Nicole Fawcette also said the project does not mean the studio is abandoning the storylines of Gears 4 and Gears 5.

Rank #3
Gears of War 3 (Renewed)
  • Disc only. Original case and manual not included. Will come packaged in a generic case.
  • This renewed game has been cleaned, tested, and shows minimal wear.

In practical terms, you can understand E-Day as a prequel: it moves back to the start of the Locust War while remaining part of the main series. It provides earlier context rather than replacing the events or continuing directly from the later games.

What platforms is it on, and when did it release?

As of October 7, 2026, the Xbox product page lists Gears of War: E-Day as released on October 6, 2026, for Xbox Series X|S and PC.
