Show HN: Make any game multiplayer with one prompt
A new tool called Antics allows developers to add multiplayer functionality to any game using a single prompt, simplifying the process of making single-player games playable with others.
Background
- The site (antics.gg) lets you turn single-player games into multiplayer by entering a single prompt — likely by injecting network code or cooperative/competitive logic into a game's runtime.
- This kind of "modding" has traditionally required deep reverse-engineering and programming skill. A tool that does it from one prompt suggests a large language model or specialized AI is handling the heavy lifting of code generation and game state interception.
- "Make any game multiplayer" is a long-time dream in the gaming community; similar past attempts include Nucleus Co-op (which splits one PC into multiple game instances) and split-screen mods for specific titles, but those require manual setup per game.
- The submission is on Hacker News (HN) under "Show HN," meaning the creator is presenting a working project for feedback. This gives it credibility as something actually built, not just a concept.
- Why it matters: if the tool works as claimed, it could dramatically lower the barrier for playing older or single-player-only games with friends, and it represents a new category of AI-assisted game modding.
