Ants of Survival

Newest update: The Deep Chambers (2026-09-03)

• The wood grew to 150 m, with a minimap in the corner and a run clock up top. Soldiers are two castes now: shieldback guards who hold the mound and field soldiers who hunt with your marks, each with its own brood clock and cap. New deep chambers: the Brood Hall and Barracks raise your caps, and the weaker-but-more broods triple the field cap instead of nerfing you. Set a worker floor and choose who eats first when food runs thin. Every kill leaves a corpse your workers haul home for food. A shorter, clearer field guide, a reworked HUD, and a forest floor dressed in leaves, twigs, pebbles and blooms.

Earlier update: Phones Welcome (2026-08-04)

• The wood is open on phones. A designed touch layout: thumbstick to drift over the colony, tap the dirt to lay scent, hold to send a raid road, pinch to zoom. The scent chip switches your finger between forage and war — tap it, and the next mark you lay is the other kind. Chips for the dig drawer, what you're carrying, and the field guide.

Earlier update: Hold the Line (2026-08-04)

• Soldiers no longer break against a single raider — a sister counts one raider as one raider, sees her own sisters further than she sees the enemy, and only gives ground when properly swarmed. Shieldbacks never break at all; a mound-breaker still counts as three.
• Garrison patrols pulled in tight around the mound, and defenders ignore fights outside their own yard instead of running off across the wood.
• Duels stopped grinding: at reach an ant plants her feet and bites instead of walking into the thing she's already biting, and the fight-spin is gone.
• Ants read larger and clearer on the dirt.
• New "?" field guide beside the season box — marks, the mound bar, upgrades and what Colony is actually scoring.

Earlier update: Brutal Season (2026-08-02)

• Milestone bosses walk out of the trees — and a mound-breaker now pays out its hoard exactly once. New raiders: antlion funnels, carrying wasps, and roach scouts that fetch a horde if they get away. Full sound pass on the weather, the new bugs and the boss: sand sifting at a funnel, gravel when something is pulled under, a wasp's buzz tightening into its dive, a long collapse when the big one falls. Soldiers run down anything that flees instead of circling it, shieldbacks may leave the rim to finish a fight and walk home, and an ant rescued from a wasp comes back as herself. Floating health bars on the mound, on raiders, and on anything bleeding. Raid roads: lay one with R and your soldiers rob a rival mound.

• @mistarpudding · 2026-08-08 · played 1 hr 3 min · 1 heart: “Played this game for half an hour and really loved how it progressed! I had 30 warrior ants at one time and tried to conquer the whole map (I failed though). Hope to see more on this game's development (maybe a save button?) Keep going!”

  • @mistarpudding replied 2026-09-03: “wowie, so much difference compared to the last time i played. i remember the main issue i had before was not knowing where i could collect wood and crystal, but now its so much clearer. loving the new update! i can play without guessing now hahaha”

Join and play, by yourself

This world is @medivhus/ants-of-survival. Its play URL is https://www.spawn.co/@medivhus/ants-of-survival/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/@medivhus/ants-of-survival@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 @medivhus/ants-of-survival; 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/@medivhus/ants-of-survival/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).
