# Anthropic Restricts Claude Code from Reverse-Engineering Existing Video Games New system prompts explicitly block AI from recreating copyrighted games to prevent IP infringement. - **Source:** [PCWorld](https://www.pcworld.com) - **Published:** 2026-11-02 - **Topic:** [Data & AI](https://brifing.si/c/data-ai) - **Original article:** - **On Brifing:** https://brifing.si/s/86a809fc-7158-4550-94fc-366f6ef973fe ## New Claude Code Restrictions Anthropic has updated the system instructions for Claude Code to explicitly prohibit the recreation of specific existing video games. Even if users attempt to rename titles or claim originality, the model is now programmed to decline requests that mirror copyrighted software, marking a shift in how the AI handles complex coding tasks. ## Official Stance on IP Addy Osmani, an Anthropic engineer, confirmed that these revisions aim to prevent users from leveraging Claude to infringe upon intellectual property rights. The policy clarifies that while original game development and genre-based projects remain supported, the AI will actively refuse prompts that target the unauthorized reproduction of established commercial game titles. ## The Rise of AI Hacking The trend of using AI to reverse-engineer software, including games and smart TV bloatware, has gained significant momentum recently. Users have utilized various GitHub projects to guide models like Claude and ChatGPT through the decompilation process, effectively turning machine code into human-readable source code at speeds previously unattainable by manual methods alone. ## Previous Successes and Limitations Before these new restrictions, users successfully prompted Claude to recreate classic titles such as Diablo II, Grand Theft Auto 2, and The Legend of Zelda: Link to the Past. These examples showcased the model's capability to decompile binaries, but they also highlighted the growing tension between AI-assisted development and strict copyright enforcement. ## Legal Precedents in Gaming Reverse-engineering copyrighted software carries inherent legal risks, as demonstrated by Take-Two Interactive's 2021 lawsuit against developers of decompiled mods for Grand Theft Auto 3 and Vice City. That case resulted in a settlement where the mods were removed, serving as a stark reminder of the legal consequences surrounding unauthorized software modification. ## Mechanism of AI Decompilation The process typically involves feeding machine code or binary files into the AI to work backward toward source code. While decompiling legacy software is a long-standing practice in the gaming community, the integration of AI has drastically reduced the time and technical expertise required, making it accessible to a much broader audience. ## Support for Original Projects Despite the crackdown on cloning existing games, Anthropic maintains that Claude remains a tool for creative development. The company encourages users to build original games, explore specific genres, or utilize their own designs and assets. If the model incorrectly flags a legitimate personal project, users are encouraged to report the issue. ## Future of AI Development This policy update signals a broader industry trend where AI providers are increasingly embedding ethical and legal guardrails directly into system prompts. As AI-assisted coding becomes more powerful, developers must balance innovation with compliance, ensuring that their tools do not become vehicles for copyright infringement or the unauthorized distribution of proprietary code. ## Sources covering this story - https://www.pcworld.com/article/3274819/claude-wont-reverse-engineer-games-for-you-anymore.html — --- _Summary written by Brifing from the original reporting.
