Marvel Rivals Version 20260604 Patch Notes: New Mantis & Iron Man Bundles, Hero Fixes

Marvel Rivals' Version 20260604 update arrives June 4, 2026 with no server downtime, adding new Mantis and Iron Man store bundles plus hero fixes for Black Cat, Rogue, Moon Knight, and Jeff the Land Shark. Developer NetEase also teases that Cyclops is coming soon.

Marvel Rivals is rolling out its Version 20260604 update on June 4th, 2026, at 09:00 UTC, and the patch arrives with zero server downtime — players simply update and jump back into the Chronoverse. The release pairs two new premium store bundles for Mantis and Iron Man with a round of targeted hero fixes and quality-of-life tweaks affecting Black Cat, Rogue, Moon Knight, and the perpetually beloved Jeff the Land Shark.

New Store Bundles: Mantis and Iron Man Get the Spotlight

The headline additions for this patch live in the in-game store, where two heroes receive fresh cosmetic bundles on a limited timetable. NetEase Games is leaning into seasonal flavor with both drops, each carrying its own availability window.

• Mantis – Mandy Celestine: The Greeter Bundle — a limited-time offering live from June 5th, 2026, 02:00 UTC through July 3rd, 2026, 02:00 UTC.
• Iron Man – Iron Samurai Bundle, accompanied by the matching Iron Samurai Emoji Bundle — both available starting June 5th, 2026, at 02:00 UTC.

The Iron Samurai look continues the game's recurring fascination with reimagining Marvel icons through different cultural and aesthetic lenses, giving Tony Stark a feudal-Japanese makeover that pairs neatly with its dedicated emoji set.

Hero Fixes: Black Cat and Rogue Get Bug Squashes

On the balance and bug-fix side, the patch resolves two oddities that affected hero abilities in specific team compositions. Both fixes restore intended behavior rather than retuning numbers, so players should not expect sweeping power shifts — just more reliable interactions.

• Black Cat's Aquatic Blind Spot: A bizarre interaction is fixed where, if Black Cat and a teammate were swallowed by Jeff the Land Shark's Ultimate Ability, her active Faltine Flame Orb would lose its Reveal effect. Felicia Hardy's mystic surveillance now works even underwater.
• Rogue's Force-Field Friction: A kinetic anomaly is resolved in which Rogue's Team-Up Ability, Hearts as One, would occasionally fail to deal its intended explosive damage when the blast collided with the Invisible Woman's force shield. Rogue's area damage now correctly affects enemies positioned around Sue Storm's barrier.

Other Fixes: Streamer Mode, Moon Knight, and Jeff's Endless Groove

Beyond the hero-specific corrections, the update cleans up a privacy bug, a cosmetic glitch, and adds a small but crowd-pleasing emote tweak.

• S.H.I.E.L.D. Encryption Secured: A UI bug in Streamer Mode that failed to conceal the other party's nickname inside Private Chat windows is fixed, restoring the mode's anonymity protections for content creators.
• Khonshu's Restored Relic: A visual anomaly that caused the Ankh jewel textures to vanish from Moon Knight's Suave Spector costume has been corrected, returning the artifact's intended luster.
• Jeff's Endless Groove: Jeff the Land Shark's Primal Groove emote now plays in a continuous loop, letting the fan-favorite hero keep dancing as long as the player likes.

What This Means for Players

Version 20260604 is a maintenance-and-cosmetics release rather than a meta-shaking overhaul: there is no downtime, no number-crunching balance pass, and no new playable hero in this drop. Instead, players get reliability fixes that matter most in coordinated team play — particularly the Black Cat and Rogue corrections — alongside two fresh store bundles to chase before they rotate out. With developer NetEase explicitly teasing that Cyclops is "right around the corner," this lightweight patch reads as a bridge to a larger content beat. Players who want the limited Mandy Celestine Mantis bundle should note its July 3rd cutoff and grab it before the window closes.
