Helldivers 2 Drops GameGuard for Easy Anti-Cheat Today: What Changes for PC Players

Helldivers 2 is replacing nProtect GameGuard with Easy Anti-Cheat today, 20 October 2026, Arrowhead Game Studios announced on Steam this morning. The studio is also adding security measures aimed at cheat mods, and warns that some mods, including harmless cosmetic ones, may stop working until their creators update them.

This explainer is built on Arrowhead's announcement and its FAQ, the Helldivers 2 Steam store page and Steam's own player data, all checked on 20 October 2026 around 06:35 UTC, plus earlier reporting by Insider Gaming and VideoGamer on the studio's position on GameGuard.

What changes in Helldivers 2 today?

Two things, according to Arrowhead. First, extra security measures to crack down on cheat mods the studio says have been circulating recently. Second, the switch from GameGuard to Easy Anti-Cheat (EAC), which Arrowhead says comes with additional security tools on top. The FAQ attached to the post answers the practical questions most PC players will have.

Why is Arrowhead dropping GameGuard?

Arrowhead's explanation is short: its GameGuard setup "wasn't as effective as it could have been". The studio describes EAC as an industry standard used in more than 200 games and says it should better protect fair play.

The announcement is also unusually direct about what cheaters were doing. Arrowhead says some players went as far as manipulating the Galactic War itself, which breaks the shared story every squad is playing through. That is the community-wide campaign behind Major Orders and planet liberation, which our guide to how Major Orders and liberation work explains in detail.

How long has GameGuard been a sore point?

Since launch. Helldivers 2 arrived on PC with GameGuard in February 2024, and players have blamed the kernel-level tool for crashes and performance problems ever since. Arrowhead defended it for a long time: a year ago, CEO Shams Jorjani said on Discord the studio saw no evidence of a performance impact, before telling players it was "looking into" alternatives, Insider Gaming reported on 21 October 2025.

According to VideoGamer's write-up of the 2025 exchange, Lindgren had argued at launch that kernel-level anti-cheat was one of the more effective ways to stop cheating, citing a Helldivers 1 exploit that handed out research samples to everyone in a mission.

Is Helldivers 2 still popular enough for this to matter?

Yes. Steam reported 22,653 people playing Helldivers 2 at 06:34 UTC today, minutes after the announcement, and the game sat 23rd in Steam's weekly most-played chart with a peak of 46,300 concurrent players, the same rank as the week before. Those are PC numbers only; PS5 and Xbox players are not counted, and the announcement does not mention console versions.

What should PC players do now?

Update the game as normal through Steam. If you use mods, expect some to break: cheat-style mods that affect other players are the intended target, but Arrowhead says cosmetic mods may also stop working until they are updated. If EAC flags something harmless, Arrowhead asks players to contact its support on Zendesk.

The switch also lands on the same day as the Scope of Authority Premium Warbond, which Arrowhead scheduled for 20 October with the R-40 Sightliner bolt-action rifle, the P-44 Mist machine pistol and the AMW-20 Apex anti-materiel rifle. If the game misbehaves after today's download, it may not be obvious which change caused it.

What don't we know yet?

Arrowhead does not say whether its EAC setup runs at kernel level on Windows, which was the core complaint about GameGuard, and the Steam store page still listed GameGuard when we checked. It also does not promise any performance gain: that is what many players expect, but the studio's own position until now has been that GameGuard had no measurable impact. We will update this article if Arrowhead publishes patch notes or clarifies either point.
