Marvel Rivals Season 10.5: Infinity War Mode, Endgame Raid and Halloween Events

Marvel Rivals Season 10.5 launched on October 9, 2026 at 9 AM UTC. There is no new hero this time. Instead, the mid-season update continues the Path to Doomsday event with two new Avengers modes, Halloween content and new costumes. Season 11 is due on November 13.

Path to Doomsday: Avengers: Infinity War

The new PvP mode arrived on launch day and is described as a fast-paced 2v2 mode. According to Beebom’s patch notes summary, the first squad to collect all six Infinity Stones wins. The mode runs from October 9 until December 11, 2026.

Path to Doomsday: Avengers: Endgame

The second mode is a 50-player PvE raid against Thanos and his army. The version 20261022 patch landed on October 22 at 9 AM UTC with no server downtime, but the official patch notes say the mode itself officially kicks off on October 24. It runs for four weeks, until November 26, and is available only during set sessions each week. The first two sessions were scheduled for October 24 at 01:00 to 03:00 UTC and 18:00 to 20:00 UTC. Players can unlock a free Captain America costume as a reward.

Other additions

• Infinity Finale: a new event kicked off on launch day, with MCU-themed costumes in its Event Pass.
• Alchemax Headquarters: the map is now available in the 18v18 Annihilation mode.
• Twitch Drops: the Angela Will of Galacta costume and related bundle content, available until November 6.
• Balance update: a hero balance pass also arrived with the season. Check the official patch notes for the numbers.

Season 10.5 schedule

• October 9: Infinity War PvP mode, Infinity Finale event and three costumes.
• October 15: patch with the All Hallows’ Glow Halloween event and skins.
• October 22: patch adding the Endgame PvE mode, which officially starts on October 24.
• October 30: Halloween: Night of Illusions event. Some outlets list October 29.
• November 6: new costumes for Spider-Man and The Thing.
• November 13: Season 11 begins, and the roadmap points to this as the end of Season 10.5.

Early roadmap coverage listed the Endgame mode for October 22, 23 or 29 depending on the outlet. The official October 22 patch notes settled it: the patch went out on October 22 and the mode started on October 24.

Where Season 10 left off

Season 10 started on September 11 with the hero Gorr the God Butcher and a major Scarlet Witch rework. TalkEsport reported that its balance changes touched about 70% of the roster. Season 11 is confirmed to bring a new hero, according to Beebom, but the hero has not been officially named in the sources I found.

What it means for players

If you want the new content, the Infinity War mode and the Endgame raid are the main reasons to log in before Season 11. Because Endgame runs in scheduled sessions, check the in-game schedule before you plan a play session. See the Marvel Rivals game page on GameGood for more.
