People Playground hit again by malicious Steam Workshop mods

According to a Steam update cited by Kotaku, mestiez called the latest mod "extra bad" and advised players who used the game on or around September 21 to be extra cautious.

The developer urged players to remove mods from their mods folder and not reopen the game until there is official confirmation that everything is safe again.

What happened

People Playground, the PC sandbox game that launched in 2019 and has hundreds of thousands of Steam reviews, has reportedly been hit again by a malicious mod on the Steam Workshop, according to Kotaku. This is the second incident in the same year, after which developer mestiez disabled the Workshop once more. Kotaku ties the report to a Steam update from the developer and describes it as a repeat of an earlier problem involving the same mod environment.

In the Steam update cited by Kotaku, mestiez says the latest mod is "extra bad." The developer said they could not determine with certainty exactly what happened, but warned players who used the game on or around September 21. That timing matters because the warning specifically refers to users who opened or installed the game around that date.

Kotaku writes that the mod may be able to delete data, read Discord information, and publish itself to Steam as a mod in order to spread further. The provided sources do not independently confirm those claims; they are presented as possible effects rather than a full technical analysis. The available information therefore points to several suspected functions or outcomes, but not a definitive confirmation of which ones were actually carried out.

Mestiez advised players to remove mods from the mods folder and not launch the game until an official message confirms it is safe again. The supplied information does not say what specific steps Valve or Steam itself has taken. What is clear is that the developer took the Workshop offline again while the situation was being assessed.

The report fits a broader pattern in which People Playground's Steam Workshop serves as a major distribution channel for user-made content. Because the game has an active mod scene, a malicious upload can quickly draw attention and lead to a temporary Workshop shutdown, according to the reporting.

Background

People Playground is a popular Steam game with a large mod scene, making the Steam Workshop an important part of the community. According to Kotaku, the game was hit twice in 2026 by malicious mods, prompting the developer to take the Workshop offline again. The combination of an active mod community and a central Workshop makes it easy for players to install content, but also means a problematic upload can spread quickly.

The key point in the report is that the exact behavior of the latest mod has not yet been fully established in the supplied sources. What is clear is that mestiez asked players to be cautious, remove mods, and wait for an official safety notice before opening the game again. The warning is specifically aimed at users who used the game on or around September 21, suggesting the developer identified a possible exposure window.

The available information also says the mod may be able to publish itself to Steam as a mod to spread further. That detail matters because it shows how a Workshop incident can affect not just a single file, but also a distribution mechanism within the same platform. At the same time, the source stresses that this has not been fully confirmed and that the developer themselves said they could not say with certainty what exactly happened.

Kotaku also notes that the game launched in 2019 and now has hundreds of thousands of reviews on Steam. That underlines that this is an established PC title with a large user base and a long-standing presence on the platform. The report of a second incident in the same year shows that the developer once again had to disable the Workshop to investigate.

The supplied information does not say what specific measures Valve or Steam itself has taken, nor how many users were affected by the latest mod. As a result, the technical impact of the incident remains limited to what Kotaku and the Steam update cited by the outlet report. The factual core remains that mestiez issued a warning, disabled the Workshop, and asked players to remove mods and avoid reopening the game for now.
