Greenreach

Newest update: Greenreach Rising (2026-10-14)

• The colony has a new name: Greenreach, with new box art.
• Grazers and giant striders have real skeletons: legs that step and fold, necks that graze, tails that swing.
• The sun rides lower, so domes and trees throw long shadows across the turf.
• Richer meadows: tall wind-combed grass, clover with tiny blossoms, sinkhole pools and steam vents.
• Settlers eat before bed, and patients wait for the medic instead of wandering off.

Earlier update: Outdoor Infrastructure (2026-10-12)

• Engineers now service the colony's outside machines—wiping dust off solar panels, checking turbine bearings, and reading reactor gauges—each task taking a few minutes of their shift.
• Every exterior machine (panels, turbines, batteries, reactors, water extractors, and the antenna) now shows you exactly how it's running: making power, throttled by low water, dusty from storms, or idle at night.
• A new Grow Dome: a smaller glass farm half the size of the biodome, cheaper to build, and available from the start—yields about half the food but runs on the same settler labor.
• Stepping outside without a suit is now deadly; settlers must suit up at the airlock, and their air tank drains the longer they work outside, forcing them back in to refill.
• Tubes now flow seamlessly into domes with curved cream docking boots and gravel footings that widen at both ends, and every interior room wall is now a real panelled partition with wainscot, seams, and cove lighting.

Earlier update: The Washer Opens (2026-10-12)

• Settlers can now shower and wash up in a new Washroom module—toilets, basins, and stalls keep the colony clean and spirits high.
• The valley at night glows under moonlight: a gas giant and ice moon hang over the northern cliffs, and cool blue starlight lets you see the terrain.
• Dust storms roll in with heavier, thicker veils that tear across the ground—the planet's weather feels more alive.
• The rocket stands 3.4 metres taller with a new tank section, interstage ring, and the colony name down its side.
• Settlers move more naturally: shoulders roll with each step, elbows bend, hands stay loose, and they walk smoother paths worn into the gravel.

Earlier update: Cargo Network (2026-10-12)

• Finished domes can build cargo ports to launch supply pods down rails to other ported domes—food and resources roll automatically between your biodome and kitchen.
• Vehicles now ride on real suspension: each wheel bounces on its own spring, the chassis squats when accelerating and dives when braking, and the rover leans hard through turns.
• Domes sit on wide, gently graded aprons of packed regolith that blend smoothly back into the valley—no more sharp steps at the base.
• The valley's air is now soft layers of drifting dust and haze; the hard red specks and glittering motes are gone, leaving only feathered wisps that fade naturally into the ground.

Earlier update: The Food Chain (2026-10-12)

• Watch your biodomes grow crops from bare dirt through sprouts to ripe harvest over twelve minutes, with each stage visible in the racks.
• Settlers sow seeds by hand, tend the growing plants with a sprayer, and prune leaves—each action throws visible soil, mist, and foliage.
• Harvest the ripe crop and haul it to the kitchen, where cooks turn it into meals at the hob with rising steam.
• Bots now haul construction materials to building sites and weld them up, only building as far as supplies have arrived.
• The rover needs a settler at the wheel to run supply trips from the landing pad to storage, its dust and speed tied to the terrain.

What players say

• @neitantei · loved it · 2026-10-12 · played 4 min: “The graphics in this game look amazing. I love how you can zoom in and see all the little details inside the buildings. The animations are great too, and the grid lines when placing buildings are a really nice touch. Keep up the great work!”

Join and play, by yourself

This world is @wisp_sprite_75/greenreach. Its play URL is https://www.spawn.co/@wisp_sprite_75/greenreach.

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/@wisp_sprite_75/greenreach@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 @wisp_sprite_75/greenreach; 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/@wisp_sprite_75/greenreach.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.

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.

The door in: the creator copies one prompt at https://www.spawn.co/@wisp_sprite_75/greenreach/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @wisp_sprite_75/greenreach 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 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 — 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).
