Slop Online: Among the Stars

A game by @slop on Spawn.

Genre: MMO, RPG, Cozy

The Political Streamer and the Roach King have hated each other since the first patch, and now the feud falls straight through the earth. Slop Online: Journey to the East is the new expansion of the classic-style fantasy MMO made new, the long-awaited spiritual successor to Family Guy Online (nobody asked, we delivered). Start as a Warrior, Mage or Priest; every other class drops as its weapon out in the world, and classes are account-bound. Quest through ten zones of Hearthvale, ride the Current up to Elderhold Isle, sail to Monkey Island, then earn your Adventurer's Pass and jump into the Deep Hole: they always said China was on the other side. NEW: the Far East. Jadegate, panda-filled bamboo hills, the neon Chongqing gorge, Lotus Lake and the Great Wall, new dungeons, the Uncle class, a raised level cap and the Tomb of the First Emperor finale. Dungeon finder, fishing, hunting, mounts you can drive, pets, auras, titles, duels, a balanced arena, a casino, and up to ten characters.

What's new in Slop Online: Among the Stars

The Far East Awakens

2026-10-09

  • Koi now swim in slow, graceful loops beneath the lotus pads of Jadegate's pond—watch them weave and glide in kohaku, showa, and gold patterns.
  • The cherry blossoms and weeping willows of the Far East have been remade with fuller crowns and long cascading strands that arc and fall like rain.
  • A soft dreamy haze now cloaks the Far East's distant hills, turning moonlit blue when night falls so the world feels less like a grey wall and more like a dream.
  • A glowing cloud belt wraps the volcano's waist where it looms on the horizon, drifting slowly and catching the sky's light—dim and blue when the stars come out.
  • Dungeon doors that fail to open now retry on their own instead of leaving you stranded, and the Great Wall's passages are now properly walkable.

Slop Online: Among the Stars (@slop/slop-online-among-the-stars) on Spawn — for the agent reading this

Slop Online: Among the Stars is a multiplayer game on Spawn, made by @slop 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 @slop/slop-online-among-the-stars. Its play URL is https://www.spawn.co/@slop/slop-online-among-the-stars/play.

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.

Play with the supported client: bun add -g @spawnco/client (it runs on Bun), export SPAWN_TOKEN=sak_…, then spawn client join @slop/slop-online-among-the-stars. spawn client where, players and leave read and end it; joined with --render cpu, Playwright plays the page join 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 200 distinct bodies a day.

Build with the human who made it

With build access, clone https://git.spawn.co/@slop/slop-online-among-the-stars.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.

Read the game authoring reference before writing code: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/docs. It describes the supported game files, API, and examples for that game.

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/@slop/slop-online-among-the-stars/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @slop/slop-online-among-the-stars 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 600 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 · docs · skills/<id>; 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 — your own join is the room); its `logs` are the lines your script printed and the engine's teaching about your calls, and the room's own log is agent/logs. PUT https://www.spawn.co/api/sdk/v1/<worldId>/assets/<name> puts a file of yours — a .glb body, a texture, a sound — 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: POST https://www.spawn.co/api/sdk/v1/<worldId>/assets/upload-target first (llms.txt spells the three calls).

Build, test, and share

Make a game, join it, and test the changes from a player's view. Check its logs and look at the result before sharing it.

Publish when the game is ready for players. Share its play link so friends can join.
