Obsidian Temporarily Pulls Multiple Games from Storefronts Over Unity Security Flaw

Obsidian Entertainment has temporarily removed several of its games from digital storefronts following the discovery of a security vulnerability in the Unity engine.

For anyone familiar with Obsidian’s work, this is the studio behind acclaimed RPGs like Fallout: New Vegas, Pillars of Eternity, and The Outer Worlds. This year alone, it’s already had Avowed and Grounded 2 enter the spotlight, with The Outer Worlds 2 still slated for release on October 29, 2025. But now, due to a newly reported Unity security issue, many of its titles have been pulled from Steam, Xbox Store, PlayStation Store, and other digital platforms.

In a statement shared on X (formerly Twitter), Obsidian confirmed that it had taken down multiple titles as a safety measure after a Unity-related vulnerability was identified. The post didn’t specify the technical details but emphasized that this was a precautionary move to protect players and systems while updates are prepared.

Here’s the list of affected titles that are currently unavailable:

• Grounded 2: Founders Edition

• Grounded 2: Founders Pack

• Avowed: Premium Edition

• Avowed: Premium Edition Upgrade

• Pillars of Eternity: Hero Edition

• Pillars of Eternity: Definitive Edition

• Pillars of Eternity II: Deadfire

• Pillars of Eternity II: Deadfire Ultimate Edition

• Pentiment

According to the studio, players who already own these games should wait for the upcoming patch before launching them again. Once fixes are applied, the games will return to storefronts.

Unity staff member Major Nelson also issued a statement on the Unity forums, stating the flaw affects games and applications built on Unity versions 2017.1 and later, across platforms including Windows, macOS, Linux, and Android.

Nelson noted that there’s no evidence of the vulnerability being exploited so far. “Unity proactively provided fixes that address the vulnerability, and they are already available to all developers,” he wrote, adding that developers are being encouraged to update their products as soon as possible.

Windows, Steam, and other platforms have already implemented the necessary fixes at the system level. However, some studios like Obsidian chose to take their titles offline temporarily to apply patches manually and ensure player safety.

For now, the best thing players can do is uninstall the affected games or avoid launching it until patches are released, as per the Microsoft guideline.
