Valve has updated the Steam developer portal with a new edit section dedicated to anti-cheat software. Going forward, it's asking developers to disclose if their game uses anti-cheat technology like PunkBuster, and mandating they do so if they use client side, kernel mode anti-cheat.The shift in position on kernel mode anti-cheats follows years of back-and-forth between players and developers on anti-cheat software that can interfere with consumer hardware. Because kernel-level access is so highly privileged, accessing it means players are placing a lot of trust in developers and risking wide-ranging consequences if a nasty bug in the anti-cheat software could wreck an entire PC.But developers using kernel mode anti-cheat have justifiably held firm, as kernel mode checks on some games are needed to prevent devastating cheating that could demolish a multiplayer ecosystem. The back-and-forth has been frustrating for everyone involved.According to Valve, the requirement for kernel mode anti-cheat disclosures is retroactive and applies to game already listed on Steam. The company said it's reaching out to developers with games that use the technology. It'll also be part of future release reviews.Developers who already disclose anti-cheating tech in their store pages will still need to update this new section.Image via Valve.For those using conventional anti-cheat tools, Valve says it won't mandate they share that information but that it "generally think[s] that any game that makes use of anti-cheat technology would benefit from letting players know.How high are the stakes in the fight against cheaters? So high that Destiny 2 and Marathon developer Bungie has won millions in court suing cheating software developers, and even smaller developers like Splitgate 2 developer 1047 Games are buying out companies with anti-cheat tech to keep their games safe.
