Analysis

Avowed Studio Obsidian Removes Several Games From Sale Due To Unity Security Issues Though Avowed itself runs on Unreal Engine 5, the RPG was still affected. A vulnerability found in the Unity game engine has led to studio Obsidian Entertainment taking down five of its games, including the premium edition of its 2025 release Avowed. The Unity issue, discovered in June and patched on October 2, could have allowed "local code execution and access to confidential information on end user devices running unity-built applications," reads an advisory on the official Unity website. Although Unity states that there is no evidence of any impact on users, developers are still recommended to "rebuild your games and applications with updated Unity versions." In response to the discovery, Obsidian announced on Friday that it had temporarily removed some of its titles from digital storefronts to "implement the necessary updates" toward the security issue. Along with Avowed Premium Edition, Obsidian also removed the Grounded 2 Founders Edition and Founders Pack, Pillars of Eternity: Hero Edition and Definitive Edition, Pillars of Eternity II: Deadfire and its Ultimate Edition, and Pentiment. A security vulnerability affecting our games that use Unity has recently been identified. — Obsidian (@Obsidian) October 3, 2025 As a precaution and to keep you safe, we have temporarily removed the following titles and products from digital storefronts while we implement the necessary updates to address the issue:… "Our team is working on a fix and will restore these games as soon as possible. We will provide additional information once they are available again," Obsidian said in an X post, which also encouraged those who have the affected games installed to update them when patches become available. Pentiment and both Pillars of Eternity games run on Unity. While Avowed and Grounded 2 run on Unreal Engine 5, Obsidian clarified on X that Unity is used for the digital artbook included with Avowed Premium Edition. Grounded 2, which is currently in early access, also includes an artbook in its Founders Pack, though Obsidian didn't explicitly confirm if this artbook was also built in Unity. Obsidian was far from the only studio affected by the security vulnerability, with Unity-built titles including Overcooked 2 and Among Us receiving quick patches in response to the issue, while the PC version of Fallout Shelter still remains delisted.

Email [e-mail] Join the conversation A significant security vulnerability in Unity's (U) game engine, which could permit local code execution and access to confidential user data, has prompted material preventative actions from game developers, creating a direct headwind for Unity. Despite Unity releasing a patch on October 2, prominent studio Obsidian Entertainment has temporarily delisted five titles, including the premium edition of its 2025 release Avowed, to implement necessary updates. This reaction underscores the severity of the flaw and the operational disruption it causes for developers, who are forced to halt sales and divert resources to remediation. The incident's impact extends even to games not primarily built on Unity, as seen with Avowed's Unreal Engine 5 build being affected due to an artbook component made with Unity software, highlighting the engine's deep integration and the associated systemic risk. The highly negative sentiment score of -0.7 for Unity's ticker reflects significant market concern regarding reputational damage and the potential erosion of developer trust, a critical asset for a platform-based business model.

Key Decisions for Investors

• Investors in Unity (U) should closely monitor developer sentiment and any commentary on platform reliability, as this security incident could damage long-term relationships and potentially slow new project adoption on the engine.
• The delisting of games represents a direct, albeit temporary, revenue disruption for publishers, highlighting a key operational risk for investors in the gaming sector tied to third-party engine dependencies.
• A cautious or short-term bearish stance on Unity may be warranted until the full scope of the fallout is clear, as the reputational damage and the cost borne by its developer clients could translate into future financial headwinds.
