Newest update: Mittens trailer, slime core and sign (2026-10-29)
- New trailer: a rat vs Mittens the cat. Slime Core has a new icon. The train destination sign moved to the left of the yard. Fired Cap Sling caps no longer pay the lucky bonus, crafted spares keep their own quality, and buff items stay in your bag after a raid.

@jeon · loved it · 2026-10-29 · played 7 min: “Haha, this is great! I love collecting items outside my hole and crafting weapons, but bro, why do I keep losing to cockroaches? Even the cat is way too fast haha. Maybe add a starter weapon or skill to make fighting and collecting easier!”
@makeriffic · loved it · 2026-10-29 · played 14 min: “Being a rat scavenging for items is not something I expected to play but this game is awesome man! It's well layout and gameplay is very smooth. I just wish there would be a tutorial or hints on what to do and what can be done with the looted items.”

Rat Raid is a multiplayer game on Spawn, made by @otter 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 @otter/rat-raid. Its play URL is https://www.spawn.co/@otter/rat-raid.
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/@otter/rat-raid@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 @otter/rat-raid; 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/@otter/rat-raid.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.
