The Steam Workshop for People Playground, a 2D sandbox game developed by mestiez and published by Studio Minus, was closed on September 22, 2026, after a mod was found to contain malware. The game carries roughly 300,000 Steam user reviews and an Overwhelmingly Positive rating as of September 24. The malicious mod permanently deletes a large amount of the victim's personal data, destroys Steam settings and cloud data for other Steam games, reads Discord usernames and other identifying information and posts them to the Workshop (now disabled), and automatically reposts itself to spread. Users who installed mods and played between 1:00 AM and 3:00 AM JST on September 22 are urged to run a virus scan, change their Discord password, and change passwords on all important accounts. A mod carrying malicious malware also hit the game in February 2026. People Playground is on sale for PC via Steam at 1,010 yen.
The September 22 mod is the second malware incident for People Playground this year. A mod carrying malicious code hit the game in February 2026 as well, and an earlier 4Gamer report covered that case.
The malware in the September mod wipes a large amount of the victim's personal data, breaks Steam settings and cloud saves for other Steam games, harvests Discord usernames and other identifying details and posts them to the Workshop, and reposts itself to spread to more users.
The same pattern has hit other Steam titles recently, which is why the warning now extends past this one game.
- Escape from Tarkov: a Workshop mod showed fake official warnings and account suspension pop-ups that sent users to a phishing site, and the creator was banned after some users were already affected.
- Meccha Chameleon: a mod map was reported contaminated, and the studio says the latest patch resolved it.
- Wallpaper Engine: the developer plans to remove the wallpaper type reported for malware contamination from the Workshop starting next week.
- RimWorld: a malicious mod was confirmed on the Steam Workshop there as well.
People Playground is a 2D sandbox built on physics simulation and explicit violence against stick-figure-like characters, and players can build out the field and watch the characters react. It is on sale for PC via Steam at 1,010 yen.
