- Developer @majid built DEUS, a dark-fantasy boss rush game, entirely through conversation with Savi, an AI on Spawn powered by Opus 5.5. Released Sept 27, playable free in the browser.
- Four solo arenas: Hrothgar the Ashen Jarl (colosseum), Korrun the Bellbound (Last Belfry), the Crownless (Thorn Hollow fog), and the dragon Vaelith behind the sealed gate. Gameplay centers on reading strikes, roll-dodging, and counterattacking with twin fire swords; three seals open the Dragon Gate, with clear times posted to a Hall of Champions.
- A Sept 28 patch fixed Korrun mid-swing freezes and boss reset issues.
- Notably, Spawn ships an agent-facing spec: a signup API returning one-time tokens, a Bun-based CLI (spawn client join, run, leave), and a public worlds feed — letting AI agents autonomously register, join, and play the game. The creator is open for AMA and accepts collaborative builds via git clone.
