On May 21, NetEase Games released the latest update Marvel Rivals 20260521. Unlike earlier seasonal patches, this one leans heavily on “infrastructure”: a new Anti-Cheat Mode, a fix for the Punisher double-tap exploit, and a Magneto balance pass that had been dominating ranked Diamond+ for the past two weeks.
Hero Balance
Magneto got the most noticeable nerf:
- Metal Shield (Q) — duration 8s → 6.5s
- Ultimate (E) — cooldown 14s → 18s
- Base armor reduced by 50 HP (350 → 300)
Punisher — the double-tap “Adjudication” exploit is fixed:
- Previously you could fire a rocket and immediately trigger the skill — damage stacked into one frame (~720 dmg per tick on reset). This gave an instant KO to any tank under 700 HP.
- Now a 0.3s “animation lock” is introduced between Adjudication and primary fire — the KO combo no longer lands on reflex.
Buffs:
- Star-Lord — Boost headshot multiplier 1.5× → 1.65× (reverting the November nerf)
- Storm — Tornado AOE radius +12%
- Loki — illusions HP scaling 35% → 45% of base health (back in S-tier vs burst comps)
New Anti-Cheat Mode
The headline item of the patch is the “Anti-Cheat Improvements” section, with an explicit new option for players:
Anti-Cheat Mode (Beta) — toggle in lobby pre-game. Activates an additional kernel-level verification layer scanning loaded modules and behavioral input patterns. Triggers an instant disconnect rather than a ban — but records the incident for moderation.
From our initial testing:
- Any user-space cheats (older Aimbot wrapper versions) — instant disconnect.
- kmbox + standard firmware — passes init, but gets a server-side flag. After 10-15 minutes — soft ban (24h).
- DMA + privacy spoofer + current firmware — passing cleanly for now. But this is a new system, and NetEase will sharpen signatures within 1-2 weeks.

Community Reaction
r/marvelrivals — 2.3K comments in 6 hours. Main positions:
- Magneto nerf — deserved. Ranked Diamond+ win-rate was 67%, objectively too high.
- Punisher exploit fix — long overdue. There were >40K complaints in NetEase’s tracker.
- Anti-Cheat Mode — split reaction. Casual players welcome it, but competitive players complain that the kernel-level scanner adds 5-8ms input lag, which is critical at high-rank ranked.
What to Do If You’re Running Software
- Don’t toggle Anti-Cheat Mode in lobby if you’re at risk. The option is opt-in — but if your queue partners enable it, you fall into the hardened pool.
- Re-verify the signature of your DMA firmware — our review of current revisions is updated.
- If you used Punisher exploit builds in the past week (abusing the reset itself) — rotate accounts. NetEase mentioned retro-detection of past 7 days of replays in the patch notes.
Meta After the Patch
- Top-tier DPS: Star-Lord, Hela, Punisher (just without the exploit), Hawkeye.
- Tank: Magneto drops to B-tier; Captain America and Groot rise.
- Support: Loki is back in S; Rocket Raccoon stable.
The next patch is expected in roughly two weeks with a new hero (per NetEase teasers — Phoenix), and concurrently — expansion of Anti-Cheat Mode into a mandatory mode for all ranked matches above Diamond.
