A developer who runs the Korean YouTube channel ์ง์ง๊ฒ์๋ง๋ค๊ธฐ (roughly "Making real games") has released 2149, a free 3D real-time strategy game that runs in the browser and follows the rules of StarCraft: Brood War. In a video published November 8, he says he had AI build it, with 98 commits on November 7 between a first commit at 6:19 a.m. and 10:01 p.m.
Per the trailer description, the three factions (the Coalition, the Hive and the Eidon) use Brood War's rules: the same damage formula, tech tree and supply, plus larvae, creep and pylon power. There are ten maps and a computer opponent with three difficulty levels. The game needs no install or sign-up, but its menus are only in Korean for now.
The build video's description sets out the order of work. The developer put in a rules engine using numbers carried over from Brood War first, then reworked the look, from 2D to 3D and from an office parody to a "Black Planet" sci-fi setting. He credits automated AI-vs-AI matches with keeping the game from breaking and says the video shows 30 matches per faction pairing, then a rerun after one number is changed. Every trailer clip comes from such a match, the trailer description says.
The description also gives viewers a sample prompt: change one unit's damage in the game's data file, run 30 AI-vs-AI matches from a fixed starting seed, and compare win counts before and after. Comments in the game's published code say the lobby layout was assembled from a GPT mockup and that the interface icons are GPT art.
Why it matters: keeping the rules as plain data and letting bots play many matches turns a balance change into something you can measure. It's the testing loop from our guide to having coding agents playtest games. The project also sits close to another company's game: the developer calls 2149 a learning project with no affiliation with Blizzard, and we've covered why Anthropic's Claude Code now tells its agent not to recreate specific existing games.
Caveat: these are the developer's own claims, which we haven't checked, and he hasn't said which AI coding tool he used. In a Threads post he puts the work at 9 hours, which is shorter than the 6:19 a.m. to 10:01 p.m. commit window.
The game is playable now at 2149.honeycake.io; no date for English menus has been announced.
