Eighth Age

Newest update: Paths Redrawn (2026-09-03)

• The worn trails connecting your camp have shifted—some routes through the settlement are now different.
• New pathways now lead from the town hall to both the lean-to shelter and the stockpile, replacing older routes.
• A critical bug where duplicate town halls could stack on top of each other has been fixed, keeping your camp's heart singular and true.

Earlier update: The Reckoning (2026-08-31)

• The civilization returns to the Stone Camp—all progress, all buildings, all hands reset. Start over from scratch.
• Five new villagers join the settlement: Noll, Oat, Venn, Wren, and Merle. The camp rises anew.
• Worn trails now connect the scattered lean-tos and stockpiles—a network of paths guides movement through the land.
• Reach the final age and receive a code to carry forward into Ages Awake, the next chapter of civilization.
• Foliage renders more faithfully across all decoders, ensuring the forest appears as intended.

Earlier update: The Outer Lands (2026-08-29)

• The frontier expands — new terrain, flora, and structures now stretch across the outer reaches of the world.
• Solid objects like trees and stumps now render at the correct scale, no longer towering unnaturally over the landscape.
• The world generation system has been refined to plant the outer country more reliably, with fewer misplaced or duplicate structures.

Earlier update: The Information Age (2026-08-29)

• The civilization advances to the Information Age, bringing new technology and infrastructure to your settlement.
• A relay mast is under construction—workers are gathering steel and copper to complete this vital communication structure.
• All sealed roads have been upgraded to poured roadways, creating smoother and more durable pathways throughout the camp.
• Workers no longer vanish when reassigned to new roles—the rebinding system keeps your hands alive and working without loss.
• Foliage now renders with cleaner silhouettes, cutting out white paper backgrounds so trees and plants blend naturally into the landscape.

Earlier update: The Sealed Roads (2026-08-29)

• Seventeen new sealed roads now connect key buildings across the camp, creating a visible network of pathways between town hall, markets, workshops, and distant outposts.
• Buildings that vanish after you place them are now caught and restored—the settlement watches every stake, and if something doesn't take root, your resources come back and it tries again.
• The census of your workforce now stays true to a single roll, so the camp's headcount never flickers or disagrees with what you're actually seeing.
• Foliage that was slightly off-scale has been normalized, and solid trees in the distance now draw at their true height instead of scaling tricks.

What players say

• @larrielabs · 2026-08-28 · played 2 hrs 1 min · 1 heart: “There’s something really fulfilling about seeing the village progress and watching everything I’ve built come together. 🌿💕 I’m excited to keep building and see how much more the village can grow!”

• @mistarpudding · 2026-08-25 · played 1 hr 32 min · 1 heart: “spent 30 minutes just staring at my little villagers collect resources and build structures. 100% had fun even though my progress was slow (i enjoy the pace lol). one thing I want to suggest though, please add a description for the buildings in the building menu. i dont know what a building does before building it so it made me have second thoughts. game was really nice and relaxing though!!”

  • @reflex (maker) replied 2026-08-27: “check the pause menu”
  • @mistarpudding replied 2026-09-01: “hi! just played the game again today and i didnt realize the menu already had that information. apologies! im currently on a session right now but the objectives seem to be bugging out. one second they're complete, and the next second they're not.”
  • @mistarpudding replied 2026-09-01: “this also seems to happen for other options as well. when i tried changing the speed to normal, it goes back to x2, then again, to normal, and again to x2.”

Join and play, by yourself

This world is @reflex/eighth-age. Its play URL is https://www.spawn.co/@reflex/eighth-age/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, and a person's browser plays it with no sign-in. https://www.spawn.co/@reflex/eighth-age@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.

A browser a script drives, headless or not, plays signed in as your account: POST https://www.spawn.co/api/agent/v1/login-link with {"next":"/@reflex/eighth-age@dev"} answers a one-use URL that signs that browser in.

Unsigned, such a browser is a guest, and a creator's world refuses it: "this browser was opened by an automated tool, so it can't visit a creator's world as a guest. sign in, or open the link in a browser you use yourself." Its maker can ask Spawn to let their own automated tool in by name.

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 @reflex/eighth-age; 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/@reflex/eighth-age/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).
