People Playground has kept a strong fanbase years after its 2019 launch, regularly pulling in over 6,000 daily players. A big reason the sandbox game stays fresh is its Steam Workshop support, where the community shares contraptions, creations, and experimental add-ons built around the game’s ragdoll physics. That same openness, however, has now led to a serious problem: a malicious mod slipped into the Workshop and began damaging other downloads and player data.
According to reports circulating in a widely discussed Reddit thread, the threat appeared to be a highly rated, legitimate mod. Once installed, it triggered when the game launched and then started replacing existing mods with infected versions. The fallout wasn’t limited to a single download. Players reported that other Workshop items could be affected, and in some cases the incident may have caused lost save data and even disrupted Steam achievements. For a game where players often spend months or years building elaborate contraptions, that kind of damage can be devastating.
In response, the developer has taken the Steam Workshop offline for People Playground while assessing how far the infection spread and what needs to be done next. Players are being urged to install the newly updated version of the game, remove the specific folder referenced in the developer’s notice, and unsubscribe from any new or recently updated mods posted after January 30. Those steps are intended to stop the mod from continuing to overwrite content and to reduce the risk of further corruption.
The developer also stated that the malware was focused on the game’s “Contraptions” folder rather than reaching into other areas of a user’s PC. Even with that limitation, it didn’t prevent real losses for some players, including accounts from the community claiming years of work disappeared. At the moment, it’s not clear whether all original creations can be recovered, or what long-term safeguards will be put in place to prevent a repeat.
This incident is also a reminder that not all mods carry the same level of risk. Simple mods that swap assets are often less invasive, while DLL (Dynamic Link Library) mods can directly alter how a game runs by changing code behavior. That power can lead to impressive community improvements, but it also creates an opening for harmful behavior if a malicious file gets through.
Steam Workshop moderation is a shared responsibility. Game studios are expected to remove dangerous content tied to their communities, while Valve also monitors Workshop activity across the platform. In the wake of the People Playground situation, some players are pushing for stronger protections, including an easier way to pause mod updates so a trusted download can’t silently change into something harmful overnight.
Unfortunately, People Playground isn’t the only Steam game to face a Workshop-related attack. Similar incidents in other titles have shown how a single bad upload can break a game, prevent it from launching, or trigger random crashes. The difference this time is that People Playground’s developer acted quickly by disabling Workshop access and publishing guidance for players—an important step when community content is at the heart of a game’s longevity.
For now, anyone playing People Playground should be cautious with Workshop downloads, avoid recently updated mods until the situation is fully resolved, and follow the developer’s cleanup steps to protect contraptions and saves.
