The Ultimate Guide to Gears of War: E-Day's Horde Siege
Gears of War: E-Day is The Coalition's prequel set 14 years before the original Gears of War, following young Marcus Fenix and Dominic Santiago during the first Locust invasion. Built in Unreal Engine 5, it launches on October 6, 2026, for Xbox Series X|S and PC, including day one on Game Pass.
Its biggest multiplayer addition is Horde Siege, a reimagined version of the series' classic co-op survival mode.
Launch Preparations
According to GamesRadar, the game launches simultaneously worldwide at 3 PM UTC.
- Preload: Available from September 29
- Early Access: October 1 for Premium and Collector's Edition owners
- Full launch: October 6, including Game Pass Ultimate and PC Game Pass
- Install size: About 115 to 120 GB

💡 Note: On Xbox consoles, online campaign co-op, Horde Siege and Versus require a Game Pass subscription that includes online multiplayer.
How Horde Siege Works
Horde Siege supports up to 12 players split into three squads of four. As Wikipedia notes, unlike earlier Horde modes, multiple squads operate at the same time across one large map.
- Shared objectives: Squads can complete their own missions while contributing to shared goals
- Extraction: Players must survive and extract at the end of a run
- Launch maps: Three Horde Siege maps, set across the city of Kalona
- Playlists: Fan guides list Blitz, Siege and full Horde runs of different lengths
Horde Siege Classes
Four classes are available at launch:
- Assault: Frontline combat
- Breacher: Close-range pressure
- Marksman: Long-range support
- Medic: Healing and revives, including players from other squads
There's no required squad composition, so teams can experiment freely.
Updated Versus PvP
E-Day brings back 4v4 Versus with the biggest multiplayer changes since Gears of War 3.
- New controls: Cover moves to A, sprint to left-stick click, and vault and jump to Y
- Better mobility: Updated movement and traversal create more flanking options
- Post-launch plans: The Coalition has confirmed limited-time Versus modes
