Arrowhead Game Studios moved Helldivers 2 from GameGuard to Easy Anti-Cheat on October 20, and used the same announcement to publish the co-op shooter’s first explicit modding policy. The studio framed both changes as protection for the Galactic War, the shared campaign that every Helldivers 2 player feeds into, rather than as a purely technical swap.
The switch came with an unusually direct assessment. Arrowhead said its GameGuard implementation “wasn’t as effective as it could have been,” and described Easy Anti-Cheat as “an industry standard used in over 200 games.” The studio is pairing EAC with additional, unnamed security tools aimed at cheat mods that have been circulating.
The modding stance is new. Arrowhead said it had previously commented on mods only to warn that it could not guarantee their safety. The new policy splits mods into two groups: cosmetic and non-gameplay mods, which the studio welcomes, and mods that create unfair advantages or tamper with the game, which the new measures target. The studio cautioned that some mods may stop working and that non-malicious cosmetic mods may need updates from their creators.
Arrowhead grounded the crackdown in the structure of Helldivers 2 itself. Because every mission result feeds a single galaxy-wide campaign, a cheat that inflates liberation progress, samples, or mission success shifts the strategic map for every player, including people who never installed a mod. The studio said rule-bending has gone “so far as to manipulate the war itself.”
For Steam Deck and Linux players, nothing changes. The announcement’s FAQ states compatibility remains unchanged and that no new hardware requirements were introduced. Arrowhead did not spell out how Easy Anti-Cheat’s Linux support is configured, whether certain Proton versions are preferred, or how long the compatibility promise will hold through future updates.
Other details remain open, including which cheat mods were circulating and what the additional security tools are. Players who find Easy Anti-Cheat blocking a non-destructive mod are directed to Arrowhead’s Zendesk support. The studio stopped short of publishing an approved-mod list, noting that using mods is done at the player’s own discretion.
