You can earn the Infinity Gauntlet accessory for free in Marvel Rivals by completing mission objectives in Path to Doomsday - Avengers: Infinity War. Check the event missions if you want it. NetEase has confirmed that the accessory will not be sold in the store.

The store listing was corrected

The Season 10.5 patch notes placed the Infinity Gauntlet under New In Store, alongside the Phoenix Cyclops bundle. An October 8 notice in the official Discord patch-notes channel corrected that listing and confirmed the free mission reward.

That distinction matters if you were saving currency for the accessory. The correction points players to event objectives, and also names Unstable Molecules and Units among the rewards available through the event. It does not make every Season 10.5 costume or bundle free.

Check the Infinity War objectives

The mode brings 12 players into six duo squads competing for the Infinity Stones. The first squad to collect all six wins, but the accessory's unlock requirements come from the event missions. Do not assume that winning one match automatically awards it.

The correction does not list the individual missions, required totals or a separate accessory claim deadline. Check the current objectives and reward conditions in game before planning a grind around a guessed match count.

Watch the official Avengers: Infinity War mode trailer.

For the Gauntlet, start with those missions rather than setting aside store currency. Complete the listed requirements and follow the event's claim instructions.
