Marvel Rivals Season 10.5 will launch on October 9 with two major Avengers-themed limited-time modes tied to the game’s ongoing Path to Doomsday event. NetEase has revealed an Infinity War mode built around small-team battles, while a larger Endgame event will follow later in October with a 50-player PvE format. The mid-season update is unusual because it does not introduce a new playable hero, with the developers instead putting more emphasis on event content.
The first new mode, Avengers: Infinity War, begins on October 9. It uses a 12-player format split into six teams of two, with duos fighting in a series of 2v2 deathmatches set in Wakanda. That structure is a significant departure from Marvel Rivals’ standard team-based modes and is designed around repeated small-scale engagements rather than traditional six-player compositions.
Avengers: Endgame will arrive later on October 22 and takes the event in a very different direction. The mode supports up to 50 players in a large-scale PvE battle against Thanos’ forces across the ruins of the Avengers Compound. Rather than having teams compete directly against one another, players will work through a cooperative scenario built around the final battle imagery associated with Avengers: Endgame.
Both modes form part of Path to Doomsday, Marvel Rivals’ broader event roadmap inspired by major Marvel Cinematic Universe storylines. NetEase has been rolling that program out in stages, using limited-time activities and themed content rather than treating it as a single one-off event. Season 10.5 advances that roadmap with its most substantial playable additions so far.
The absence of a new hero is also notable. Marvel Rivals has established a regular cadence of major roster additions, but Season 10.5 breaks from that pattern while the team focuses on the Infinity War and Endgame content. NetEase has indicated that this is not intended to become the new normal, with the usual hero-release rhythm expected to resume in Season 11.
Season 10 itself began in September with Gorr the God Butcher as its headline addition. The season has also included new cosmetics, events and broader balance adjustments, while the mid-season update is shifting attention toward more experimental modes. That makes Season 10.5 less about roster expansion and more about giving existing heroes different environments and objectives to play around.
The Infinity War mode should create a very different balance environment from normal Marvel Rivals matches because only two heroes are paired together at a time. Strong duos with complementary defensive, mobility and burst-damage abilities could become particularly important, while compositions that normally rely on full-team support may be less effective. NetEase has not yet detailed every rule governing respawns, elimination conditions or hero restrictions, so the final competitive dynamics will depend on the full mode rules.
Endgame’s 50-player PvE setup is even further removed from the core game. Marvel Rivals is primarily built around competitive multiplayer, so a large cooperative battle against AI-controlled enemies represents a much broader experiment with what the game’s combat systems can support. The mode’s scale also makes it one of the most ambitious limited-time events NetEase has attempted since launch.
Seasonal experimentation has become increasingly common across live-service shooters, with games using temporary modes to test ideas outside their standard competitive structures. Fortnite has similarly continued to rotate major event formats alongside changes such as its move to Trios for FNCS 2027, while other multiplayer games use mid-season updates to introduce alternative rulesets without permanently altering their core modes.
Marvel Rivals Season 10.5 is set to begin on October 9, with Infinity War available first and Endgame following on October 22. Both modes are limited-time additions tied to Path to Doomsday, while the main competitive game will continue alongside them. With no new hero arriving in the mid-season update, the focus is firmly on whether these Avengers-themed modes can provide enough variety to carry the second half of Season 10.
