Vibe coders don’t know when to stop: GTA 5, Modern Warfare 2, and Halo are all playable in browsers until the lawyers come knocking
AI tools are being used to reverse-engineer commercial games and make browser-playable versions, including GTA 5, Modern Warfare 2 and Halo. Their spread matters because publishers face difficulties controlling unauthorised copies and protecting the code and ideas behind their games.
The writer says they played eight games or versions in a browser by opening a link, with no download or installation required. Some ran smoothly, while others had poor performance or graphical glitches; previously removed ports have also reappeared on copycat sites, often using less common domain extensions. The article argues that games without strong DRM may be especially exposed, while questioning whether takedowns or future laws can contain the practice.

- Takedowns have not stopped copycat sites from appearing.
New here? Start with this
Grand Theft Auto V, Call of Duty: Modern Warfare 2 and Halo are commercial video games owned by their publishers. Making them playable in a web browser can involve recreating how a game works from its software, sometimes with help from AI tools.
These browser versions may appear without the publishers’ permission, raising questions about copyright and control of game software. They can vary in quality, and copies may return on new websites after being taken down.
The issue matters to publishers seeking to protect their games and to players encountering unofficial versions online. How easily such versions can be removed or prevented is still uncertain.
Both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Browser versions can make games easier to access, preserve older titles, and demonstrate what AI-assisted reverse engineering can achieve. Supporters may argue that this experimentation expands access and encourages technical creativity, especially when original games are difficult to run or obtain.
The case against
Recreating commercial games without permission can undermine publishers’ control over their work and weaken incentives to fund costly development. Publishers may also argue that unauthorised ports risk confusing players, compromising security, and distributing imperfect versions that damage a game’s reputation.
