Marvel Rivals set the Doomsday release date for July 30th, 2026 at 09:00:00 UTC. The patch adds an Ultron invasion mode at Avengers Tower and goes live with no server downtime, so players can jump in as soon as the update lands.
The new mode puts Ultron's legion inside Avengers Tower. That gives the update a fixed start time and a clear destination for players looking for limited-time content.
Ultron at Avengers Tower
The patch is a patch and play update. That means players do not need to wait for a separate maintenance window before testing the new mode, which is the practical difference between a live rollout and a staggered deployment.
The update also ties into Avengers: Age of Ultron through the Avengers: Age of Ultron - Highlights Screening in Times Square and the Avengers: Age of Ultron - Iconic Scenes Photo Ops event. Those activities run alongside the new mode, so the patch is not just adding one fight but a larger event window built around the same theme.
PS4 and the new mode
The new mode is currently not available on PS4. For players on that platform, the update still arrives at the same time, but the headline feature is missing from their side of the release.
That split matters because the patch includes Spider-Man, Hulk, Scarlet Witch, and Winter Soldier bundles starting on July 31st, 2026 at 2:00:00 UTC, plus a Spider-Man Day store tab and the return of the Spider-Man - Peter Parker: The Photographer bundle for a limited time.
July 31st store timing
The Spider-Man Day store event runs from July 31st, 2026, 02:00:00 to August 13th, 2026, 09:00:00 UTC. Players who want the returning Spider-Man bundle or the listed character bundles need to plan around that window instead of the patch time.
The cleanest unanswered piece is gameplay structure. Ultron's legion surges into Avengers Tower, but the exact objectives inside the mode are not explained, so players still do not know whether the event is built around defense, survival, or something else.
