Gears of War: E-Day's reported US$500 million cost, and what sits behind the number

The US$500 million figure attached to Gears of War: E-Day covers far more than one game, according to Windows Central. In a report published on 2 November 2026, writer Jez Corden said the total reflects work spread across six to seven years at The Coalition, the Xbox studio that makes the series.

The number first gained wide attention through Tom Henderson of Insider Gaming, who reported that the game cost upwards of half a billion dollars. Kotaku's Ethan Gach later backed that report and added a further US$100 million on top. Earlier in October, Forbes reported the game cost US$500 million to make, and Wccftech said the sum excluded marketing.

Corden wrote that Microsoft's financial auditors attributed upwards of US$500 million to The Coalition for the period between Gears of War 5 and Gears of War: E-Day. He also reported that Microsoft staff disagree internally about how that spending should be distributed across the studio's work.

The studio's history is part of the picture. Corden reported that The Coalition came out of the COVID-19 pandemic as a support developer. It helped on several Xbox games, including Avowed, Hellblade 2, Clockwork Revolution, State of Decay 3, Grounded and Grounded 2, and it contributed to an upcoming StarCraft game at Blizzard.

The studio also worked with Epic Games on The Matrix Awakens and Alpha Point, two demos meant to show what Unreal Engine 5, Epic's game engine, could do on new consoles and PCs. Corden reported that the tools and techniques from those demos were later used across other Xbox Game Studios titles in 2020 and 2021. Derek Reese, a former senior Xbox staffer, said The Coalition is "on the hook" for Microsoft's branch of Unreal Engine and the custom tools and pipelines built around it.

Corden also reported that The Coalition spent more than 18 months on a prototype that was eventually cancelled. Rod Fergusson left the studio in early 2020, and the studio was dormant for a period while Microsoft decided its future. Corden reported that development on Gears of War: E-Day picked up speed after Mike Crump was appointed studio head.

Corden said he felt the US$500 million figure being shared internally could be used to justify possible cuts, layoffs or a studio closure at The Coalition. He added that he had not heard Xbox was planning to close the studio.

The game itself is out now for PC and Xbox Series X|S, and it is included in Xbox Game Pass, a subscription service that gives players access to a library of games for a monthly fee. It can be played alone, in split-screen co-op, or with up to four players online. Its story is an origin campaign set during Emergence Day, the event that begins the series' conflict.

The game's exclusivity has also drawn comment. Mat Piscatella, a games industry analyst at Circana, which tracks sales, said making Gears of War: E-Day exclusive to Xbox "hasn't made any difference" in how many Xbox consoles were sold.

Xbox has not announced changes to The Coalition.
