Marvel Rivals is leaning hard into its Avengers crossover for the mid-season update, and the Path to Doomsday keeps rolling into two of the biggest films in the franchise. Season 10.5 brings a fast 2v2 mode built around Infinity War, a huge 50-player raid themed on Endgame, a stack of Halloween skins, and a new 18v18 map. There’s no new hero this time around.
Quick answer: Season 10.5 goes live on October 9, 2026 at 9 AM UTC with the Avengers: Infinity War 2v2 mode. The Endgame PvE raid follows on October 22, and no new hero joins the roster this update.

Season 10.5 schedule and key dates
Everything rolls out across October, with the esports finale landing in November. Here’s when each piece arrives.
| Date | What goes live |
|---|---|
| October 9 | Season 10.5 launch and Avengers: Infinity War 2v2 mode |
| October 15 | All Hallows’ Glow event |
| October 22 | Avengers: Endgame 50-player PvE mode |
| October 29 | Night of Illusions puzzle event |
| November 23–29 | Ignite 2026 Grand Finals |
Avengers: Infinity War 2v2 PvP mode
The Infinity War mode is a 12-player fight that splits everyone into six teams of two. You pick from a pool of 13 heroes drawn from the 2018 film and battle it out in a round-robin deathmatch set on the fields of Wakanda.
Each round you lose chips away at your team’s health, and a duo is knocked out of the match once that health hits zero. Between rounds you draft random upgrade cards that tweak abilities and stats, so your build shifts as the run goes on and you can adapt to whoever you’re about to face.
Each squad receives a randomly selected Infinity Stone at the start, and every Stone has its own power. Take out an opposing pair to seize its Stone, letting the teams still standing carry multiple Stone abilities into the final rounds.
Avengers: Endgame 50-player PvE raid
On October 22, Endgame trades PvP combat for a cooperative raid. Up to 50 players join forces to battle Thanos and his army amid the Avengers Compound ruins, recreating the climactic fight from the 2019 film.
Alongside the two modes, the Times Square social hub hosts Avengers-themed activities throughout the Path to Doomsday run. Taking part earns free Units, emotes, nameplates, and other cosmetics.
Halloween events and skins
The spooky season features two events. All Hallows’ Glow begins on October 15, giving players a chance to unlock Halloween outfits and cosmetics for free. Night of Illusions arrives on October 29 with an interactive puzzle challenge, much like previous seasonal puzzle events.
These heroes receive new Halloween costumes in Season 10.5:
- Devil Dinosaur
- Blade
- Elsa Bloodstone
- Deadpool
- Rocket Raccoon
- Mister Fantastic
- Invisible Woman
- Scarlet Witch
- Black Cat
Alchemax Headquarters joins 18v18 Annihilation
Season 10.5 adds Alchemax Headquarters to the 18v18 Annihilation map rotation, giving the large-scale mode a fresh battleground to fight over.
Ignite 2026 Grand Finals
The season concludes at DreamHack in Stockholm, Sweden, with the Ignite 2026 Grand Finals taking place from November 23 to 29. Twelve squads representing four regions will vie for the 2026 championship.
No new hero, and balance changes still to come
For the first time in several seasons, a midseason patch brings no new character. Gorr joined the roster when Season 10 began last month, leaving 10.5 to focus on temporary events and quality-of-life improvements.
Hero balance adjustments are still being finalized, with full details set to land in the Season 10.5 patch notes closer to launch.
