Anthropic confirmed on Monday (November 2) that it added instructions to Claude Code, especially on the Opus 5.5 model, to discourage the recreation of existing video games and AI game cloning. The measure aims to prevent the use of AI for intellectual property infringement amid a wave of clones and reverse-engineering of popular titles with generative models.
What happened?
According to Anthropic employee Addy Osmani, the company inserted two sentences into the Claude Code prompt on Opus 5.5 to steer the model away from recreating someone else's specific game. Anthropic's usage policy prohibits using Claude for IP violation. Original games, titles within a genre, and projects based on the user's own designs and assets should continue to work normally.
The change emerged after reports of developers using Claude to decompile and recreate games like Halo, GTA, and others in browsers, plus a proliferation of low-quality clones during events like Steam Next Fest. The internal instruction identified by users prevents building recreations even if renamed.
Developer complaints
Despite the intent to protect copyrights, users report that the model is also blocking legitimate tasks such as crash dump analysis, reverse engineering for modding, debugging of own projects, and even use of reverse engineering tools. Some manage to work around it by switching to previous model versions, but Anthropic says it is iterating to find the right balance.
Osmani invited reports of cases where Claude rejects the user's legitimate work. The restriction has no user-facing toggle to disable, causing frustration among creators using the tool for legitimate development.
Why does this matter?
The decision reflects the growing tension between AI's creative potential in game development and intellectual property protection. While it facilitates prototyping and experimentation for indies, indiscriminate use for clones threatens studios and saturates platforms like Steam.
