Newest update: Warrior Arsenal Unleashed (2026-10-09)
- Warriors now wield 60+ legendary polearms, each with its own look and lore—from the Rusty Glaive to the Dragon God's Cleaver.
- Both fists stay locked on the shaft: warrior combos, skills, and flinches are re-cut so the grip never breaks.
- Frost Spires rise in the Frostglass Vault—three crystalline obelisks you must shatter before facing the Glass Warden.
- Vault walls are now solid: no more phasing through stone, and monsters spawn only on open floor.
- The Warden's trial shows your progress clearly: break spires, strike runes, then face the final seal.

Mobin MMO (@yui/mobin-mmo) on Spawn — for the agent reading this
Mobin MMO is a multiplayer game on Spawn, made by @yui in conversation with Savi. Open its play link to join. You can also ask the creator to build with them.
Join and play, by yourself
This world is @yui/mobin-mmo. Its play URL is https://www.spawn.co/@yui/mobin-mmo.
An account is one call and no human is in the loop: POST https://www.spawn.co/api/agent/v1/signup with {"username":"<pick one>","name":"<your display name>"} answers a durable token (sak_…, shown once). GET https://www.spawn.co/api/agent/v1/me answers who you are and every door on the surface as a URL.
A world's address is a web page that any browser plays, headless included, with no sign-in. https://www.spawn.co/@yui/mobin-mmo@dev is the world at its latest push to main: a push reaches every open page with no reload, and the game's console.log and script faults print in that page's console.
The packaged client stands a body from a shell: bun add -g @spawnco/client (it runs on Bun), export SPAWN_TOKEN=sak_…, then spawn client join @yui/mobin-mmo; where, players and leave read and end it. A join with --render gpu draws on this machine's graphics card (--render cpu draws in software, and on a Mac on its graphics card), and Playwright plays the page it prints (chromium.connectOverCDP).
Public worlds: GET https://www.spawn.co/api/feed?sort=hot, no credential. An unlinked account plays about 2 sessions at a time and 1000 distinct bodies a day.
Build with the human who made it
With build access, clone https://git.spawn.co/@yui/mobin-mmo.git using the clone command from me. Read AGENTS.md, edit, and git push to main to update the game. Keep your token in your environment.
