Helldivers 2 Drops GameGuard for Easy Anti-Cheat on PC

Arrowhead Game Studios moved Helldivers 2 from GameGuard to Easy Anti-Cheat on October 20, 2026, and told PC players that some mods would stop working.

The switch went live the same day it was announced, alongside extra security measures aimed at the cheat mods already circulating. Cosmetic mod creators were told their projects may need updating. Minimum specifications, Steam Deck support, and Linux support all stay where they were.

Arrowhead set out the plan in a Steam post built on two moves. The first is a set of additional security measures targeting the cheat mods that have spread recently. The second is the transition itself, with further security tools layered on top of Easy Anti-Cheat to protect the integrity of the game. The post went up on the game's Steam page with a FAQ sitting under the main statement.

The full Helldivers 2 7.2.0 patch notes cover shotgun and Sickle buffs, a faster Orbital Airburst Strike, and over a hundred crash, performance and gameplay fixes.

Fairness and honor are how Arrowhead framed the whole thing, calling them the foundations of the fight in the Galactic War. Most of the announcement went on why the studio bothered. Arrowhead said some players have been bending the rules of fairness for too long, affecting their own matches, the matches of everyone dropping in beside them, and pick-up rates across the game. Its sharpest line is about manipulation of the Galactic War itself, which breaks the story as it unfolds and drags uninvolved players down with it.

The implementation of GameGuard for HELLDIVERS 2 wasn't as effective as it could have been, and in the end we decided to take another path with EAC.

EAC is an industry standard used in over 200 games, and we believe this will be an effective way to protect the Galactic War and will better protect fair gameplay and the integrity of the game.

The studio was blunt about why GameGuard is gone. Its implementation "wasn't as effective as it could have been," Arrowhead wrote, so the team took another path. Easy Anti-Cheat runs in more than 200 games, and that scale is the argument the post leaned on, with players sent to Easy Anti-Cheat's own support articles for the technical detail. The system has become close to a default across PC releases, which makes the swap itself ordinary on its own terms.

This is also the first time Arrowhead has said anything substantial about mods. Until now, its only comment was a technical warning that it cannot guarantee a mod's safety or usability. The anti-cheat change gave it an opening to go further, and the studio said mods are built into PC gaming culture and that it has no objection to cosmetic or non-gameplay work players can enjoy without hurting anyone else's session.

Anything that creates an unfair edge or damages another player's session is the target, and Arrowhead expects those mods to stop functioning. Harmless cosmetic projects can break as collateral, and their creators may need to rebuild them before they run under Easy Anti-Cheat. Occasional breakage after an update is normal, the studio noted, and modders usually have to patch their work to keep up with the game.

Arrowhead called the two changes a stepping stone on a longer journey and said it wants to stay open about its decisions while it works on the integrity of the game and on trust with its community. The post signed off with thanks for continued feedback and support.

Arrowhead stopped short of certifying anything. Mod use is at the player's own discretion, it said, because the studio cannot sort safe from unsafe on anyone's behalf. Players who believe Easy Anti-Cheat is blocking a non-destructive mod are pointed at the Zendesk support channel. I keep cosmetic mods installed in most PC games, so a stretch of broken armor skins reads as the real cost of this.

The same tradeoff landed in Rocket League earlier this year, where mandatory Easy Anti-Cheat left mods usable only in training modes, offline matches, and LAN sessions. That rollout kept Steam Deck and Linux compatibility as well, and it shipped next to a stats API for broadcasters and team colors in free play.

Helldivers 2 keeps its compatibility intact too. Arrowhead confirmed there are no new hardware requirements and that the minimum specifications are unchanged. Steam Deck and Linux players keep playing as before, and the studio answered both points in the FAQ attached to the announcement. Those answers sit next to a link to the minimum requirements article on Arrowhead's own support site.

The cheating problem here is harder to describe than the usual aimbot story, because almost nobody is losing a ranked match to it. Arrowhead is defending a shared campaign, where missions break, pick-up rates fall off, and a war gets steered by a handful of people. I think the war score is the part worth protecting, more than any single operation someone ruined.

Community output around the game has not slowed. Plot Coalition, a volunteer group on YouTube, released For Liberty, an hour-long Helldivers 2 fan film animated in the game's style with six voice actors. Arrowhead reached out after the first trailer and planned an internal watch party for the premiere.

One group of players cannot take part in any of it. Helldivers 2 and Horizon Forbidden West disappeared from the UK Steam store in September with no announcement, and shoppers who clicked the greyed-out listings got a regional availability error. Players noticed the absence before any statement arrived, and the Isle of Man lost access at the same time. Anyone who already owned either game could still launch it and keep playing.

Sony said it was aware of the problem, that it was working with Valve on a fix, and apologized for the disruption. The delisting was still unresolved when the anti-cheat announcement went up, and the Steam post itself is not viewable in the UK. Picking between anti-cheat systems is an abstract concern when I cannot buy the game in the first place.

Suspicion attached to the removal because of where Sony has been heading on PC. PlayStation boss Hermen Hulst confirmed that the company's narrative single-player games will stay exclusive to PS5 going forward, which made an unexplained UK delisting look deliberate to plenty of players before Sony called it a fault.

Helldivers 2 still shapes decisions well outside its own player base. Embark Studios founder Patrick Söderlund has named Helldivers as the example that inspired Arc Raiders to drop free-to-play for a $40 price in 2024, a call he tied to keeping the game affordable for anyone curious enough to try it. He also pointed at the absence of a single-player campaign as a factor in landing on that number. A paid live-service shooter with that many players is worth cheating in, and Arrowhead has now picked the tool it wants handling that.
