Marvel Rivals Infinity War Mode: Complete 2v2 Guide and All Rewards

Season 10.5 of Marvel Rivals skips the new hero drop and goes straight for something more interesting: a 2v2 tournament where 12 players compete as six duos for control of all six Infinity Stones. The Path to Doomsday – Avengers: Infinity War mode launched October 9, 2026, and runs until December 11, 2026. There is a free Infinity Gauntlet accessory on the table, plus several other rewards that require zero spending.

How does the Infinity War 2v2 mode work?

Select Path to Doomsday – Avengers: Infinity War from the mode list after installing the Season 10.5 update. Twelve players split into six duos, and each round pits exactly two pairs against each other on the Jungle of Wakanda map. You are not fighting all 12 players at once — it is a structured tournament where you face different opponents as rounds progress.

Every duo shares a Squad Health pool of 100 points. Losing a round costs 15 points early on, with the penalty climbing to 35 points per round as the match continues. Reach zero and your team is eliminated. Win enough rounds to survive, collect Stones from beaten opponents, and be the first pair to hold all six.

Marvel Rivals Season 10 Release Date, Heroes & Rank Reset

Season 10 drops September 11, 2026. Here's the confirmed date, leaked heroes, rank reset math, and how to climb before it hits.

What are all the Infinity Stone powers?

Each duo receives one randomly assigned Stone at match start. You cannot pick which one you get. Stones cannot be activated until Phase 4, so the first three phases are entirely about building your upgrade card stack. At Phase 7, every Stone upgrades to its enhanced form automatically.

Win a round against another duo and you take their Stone. Eliminate a team entirely (reduce their health pool to zero) and you claim every Stone they were carrying. When holding multiple Stones, cycle through them with Z and activate the selected one with G.

Which heroes can you play in Infinity War mode?

The roster is locked to 13 heroes drawn from the Avengers: Infinity War film. You cannot use characters outside this selection.

The playable heroes are: Doctor Strange, Captain America, Groot, Thor, Black Panther, Black Widow, Iron Man, Spider-Man, Scarlet Witch, Winter Soldier, Star-Lord, Mantis, and Rocket Raccoon.

For duo composition, pairs that mix a support-oriented hero (Mantis, Rocket Raccoon) with an aggressive Duelist can cover both sustained damage and recovery. Pure damage pairs need to be more deliberate about protecting their shared health pool, since there is no passive healing to fall back on between rounds.

For a deeper look at how the Infinity Stone effects interact with specific heroes in this mode, the Marvel Rivals Infinity War LTM guide covering all Infinity Stone effects breaks down each ability in further detail.

How do upgrade cards work between rounds?

Before each round begins, both players enter a Prepare Phase to select upgrade cards. These cards alter hero stats or change how specific abilities behave for the rest of the match.

In Phase 1, you choose four cards and have two refresh chances to swap out the offered selection. Phase 3 introduces Shiny Cards, which carry significantly stronger effects and can shift your entire build direction. Shiny Card choices return in Phases 7, 9, and 11.

The mistake most players make is always grabbing the highest-damage card available. If your squad health pool is already low, a defensive card that keeps you alive through the next round is worth more than an offensive bonus you might not survive to use.

How to get all free Infinity War rewards

The mode has its own dedicated mission track, separate from the broader Infinity Finale event quests. Here is every reward and what triggers it:

The Infinity Gauntlet accessory is the headline free item. Collecting 10 Stones counts across all your matches in the event, not as a single-match total. You do not need to win a match while holding 10 Stones simultaneously. Play consistently, win rounds to claim Stones, and the total accumulates naturally over multiple sessions.

What else is happening in Season 10.5?

The Infinity War mode is the centerpiece of Season 10.5, but the update adds more around it.

The Infinity Finale event runs until December 10, 2026 (one day before the mode closes), and lets you earn Thor's The Avengers costume for free by completing event quests. MCU-inspired looks for Black Panther and Doctor Strange are also part of the event artwork, though the patch notes do not confirm every pictured item as free.

Times Square has two limited activities ending much earlier, on October 22, 2026:

• Watch the Avengers: Infinity War film screening continuously for two minutes to earn the exclusive Gallery Card – Avengers: Infinity War
• Take a group photo with NPCs at the Iconic Scenes photo walls outside the Avengers' Gift Shop to earn the Avengers Emblem Spray and 100 Units

Those Times Square activities expire weeks before the main mode closes, so prioritize them first.

The Alchemax Headquarters map also joins the 18v18 Annihilation mode this season, and the Angela – Will of Galacta costume is available through Twitch Drops running from October 9 to November 6, 2026. The Season 10.5 ranked reward is the Jeff the Land Shark – Razor-Tooth skin.

Tips for winning Infinity War matches

A few things that separate teams that survive deep into the tournament from those that exit early:

• Coordinate Stone usage timing. Burning a Stone ability the moment you get it often wastes it. Time the Reality Stone's area denial around a moment when the enemy is committed to a push.
• Protect the health pool, not just your own HP. Two players losing rounds repeatedly is faster elimination than one player dying. Play for the duo, not for individual kills.
• Mind the Stone cycling. Once you hold multiple Stones, actively cycling through them with Z and selecting the right one before a fight starts is a real skill gap between players.
• Shiny Cards at Phase 3 set your build direction. The card you pick there shapes which upgrade cards are worth taking in later phases. Think two phases ahead.
• Time Stone is a panic button, not an opener. Rewinding yourself 5 seconds when you are in a bad position is more valuable than using it offensively.
