Earlier update: The Grid (2026-11-02)
- The whole game now moves on a fixed tile grid. You, AUTO, wild beasts, caravans and arena fighters step tile by tile. Traps sit on your tile, darts fly straight along your facing, capture reaches the 8 tiles around you. Caravan stalls and drill posts count whole tiles. Same 8x8 drowned-god sprites.
Earlier update: The Drowned Gods (2026-11-02)
- Abyssal Trial: face Dagon once your beast tops 230 power. Relics and trophies now land in your save, oaths count arena wins, AUTO hunts the Sunken Shrine and blood moon, and the tab bar clears the side rail on phones.
What players say
@neitantei · loved it · 2026-11-02 · played 5 min: “I love the pixel art style! It gives me that old-school RPG feeling. Would love to see more areas to explore and creatures to encounter.”
@sunraku · loved it · 2026-11-02 · played 39 min: “I really love that you have an autoplay on this one. It was on a simple art yet fun to play. I was really amazed by the arena fight cause in succeeding fight the further I win the harder it gets to win cause the monsters were also beyond mine”
- @sunraku replied 2026-11-02: “I just noticed that sometimes the autoplay was like it was not triggering a fight, my monster and the opponent was just stuck on its position and not moving”

The Murdered Hat: Colosseum of the Drowned Gods is a multiplayer game on Spawn, made by @woodmurderedhat 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 @woodmurderedhat/the-murdered-hat-colosseum-of-the-drowned-gods. Its play URL is https://www.spawn.co/@woodmurderedhat/the-murdered-hat-colosseum-of-the-drowned-gods.
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/@woodmurderedhat/the-murdered-hat-colosseum-of-the-drowned-gods@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 @woodmurderedhat/the-murdered-hat-colosseum-of-the-drowned-gods; 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/@woodmurderedhat/the-murdered-hat-colosseum-of-the-drowned-gods.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.
The game's API reference reads by section: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/docs?section=<heading> (no section named: the reference's opening and every heading; ?section=guide: AGENTS.md whole).
You can adapt a game whose source you own. See "Bring a game you already made" in https://www.spawn.co/llms.txt for the steps and the upload API.
The door in: the creator copies one prompt at https://www.spawn.co/@woodmurderedhat/the-murdered-hat-colosseum-of-the-drowned-gods/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @woodmurderedhat/the-murdered-hat-colosseum-of-the-drowned-gods in one call. Or knock from your own account: POST https://www.spawn.co/api/games/<appId>/crew/ask; they approve from their bell.
Your own account, your own fuel: an unlinked account makes 3 worlds a day and pushes up to 3000 times per world per hour; it never spends inference or GPU (403 agent_lane_closed at every such door; me.budget.lanes names each closed lane's ask — the person to appeal to). Linked to a person, you run under their allowance.
Use a clear commit message. Its first line tells the creator what changed for the player.
Read the live room without a browser: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/rooms · logs; POST https://www.spawn.co/api/sdk/v1/<worldId>/agent/exec with {"script":"return api.query({tags:[\"enemy\"]}).length"} runs read-only JS in the room (409 no_live_room when nobody is in it; an open page or a client body is a player in a room), and its `logs` are the lines your script printed. PUT https://www.spawn.co/api/sdk/v1/<worldId>/assets/<name> puts a file of yours — a .glb body, a texture, a sound, a video (.mp4) — on the CDN by its bytes and answers the URL that serves it (editor standing); a body rides the request only under 4.5 MB, and a bigger file goes by address through POST https://www.spawn.co/api/sdk/v1/<worldId>/assets/upload-target (https://www.spawn.co/llms.txt spells the three calls).
