LEVEL 118: The Darkest Campground

Newest update: The Campground Expands (2026-07-22)

• The forest thickens around you — over 360 new trees crowd the perimeter, and the dark presses tighter with each step away from the fire.
• Three new campsites bloom across the grounds: a ranger clearing to the east, a creekside shelter to the north, each ringed with fallen logs and picnic tables waiting for hands that never came.
• A dry creek bed now cuts through the northern reaches, with stepping stones and undergrowth reclaiming what the water left behind.
• Paths fork and branch — Trail A leads east to the ranger post, Trail B dips north through the creek toward the creekside camp, and a faint stub of Trail C wanders toward an old dead lantern.
• When you rekindle a light, the regenerated void sometimes tears open nearby — a fleeting exit that lasts only a minute before the dark reclaims it, unless you're fast enough to step through.

Earlier update: The Zoo Awakens (2026-07-22)

• A new enclosure has opened in the darkness—eight deer stand motionless in the gloom, moving only when your gaze shifts away.
• Facelings now circle the scattered campfires at the edge of the light-web, walking slow processions that stop when you draw near.
• Five owls perch in the high branches, always already watching you when your torch finds them, and they never leave their posts.
• The unseen thing drifts through the void around you, invisible but heard—wet clicks, hollow knocks, the sound of something heavy dragged through leaves.
• A cabinet in the forest should not be trusted; opening it summons a presence that hunts you down for nine terrible seconds.

Join and play, by yourself

This world is @0liver/level-118-the-darkest-campground. Its play URL is https://www.spawn.co/@0liver/level-118-the-darkest-campground/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.

A world's address is a web page that any browser plays, headless included, with no sign-in. https://www.spawn.co/@0liver/level-118-the-darkest-campground@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 @0liver/level-118-the-darkest-campground; 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

This game runs an engine from before 6.0 and has no repository to clone. Its creator can open https://www.spawn.co/@0liver/level-118-the-darkest-campground/code for upgrade instructions.

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.

Ask to build with the creator: POST https://www.spawn.co/api/games/<appId>/crew/ask. They approve from their bell. The code page offers an invite prompt after the game moves to 6.0.

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).
