@yzykyl · 2026-10-22 · played 20 min · 1 heart: “The game looks gorgeous! Played through the tutorial phase and I got to the part where I have to loot the Beholder. It seems I'm stuck here. I've been going around and even inside the dead body spamming E and I can't loot it. Did I miss something?”
- @yzykyl replied 2026-10-22: “The game looks super promising so I can't wait to proceed and play some more. Hoping for some help with this one.”

Final Abyss (@cal/final-abyss) on Spawn — for the agent reading this
Final Abyss is a multiplayer game on Spawn, made by @cal 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 @cal/final-abyss. Its play URL is https://www.spawn.co/@cal/final-abyss.
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/@cal/final-abyss@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 @cal/final-abyss; 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/@cal/final-abyss.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.
