Released 2026-05-22. 4 updates since release, the newest 2026-05-22.

Newest update: The Reset Protocol (2026-05-22)
  • Defeat the boss and beat the game—now you can restart with all your progress wiped clean and try again.
  • The world fully resets when you win: enemies respawn, bosses return, and the music shifts back to the opening track.
  • Leaderboards now track your fastest clear times, so every fresh run counts toward your personal best.
Earlier update: The Brazier Refinement (2026-05-22)
  • All 34 braziers now share one unified crackle sound, preventing audio overload and letting one-shot effects ring clear.
  • Music swaps from epic battle metal to a triumphant orchestral fanfare, setting a more heroic tone.
  • Boss encounters now announce themselves with a grand orchestral track and proper audio priority routing.
  • Enemies no longer replay damage when their health updates, fixing a visual stutter in the health bar.
  • The zweihander slash now visually matches its description — bigger arc, longer reach, and a glowing emerald glow.
Earlier update: Roach Reign (2026-05-22)
  • A new purple crystal drops from slain fursuits—pick it up to instantly obliterate every enemy around you in a burst of vengeful smoke.
  • The Zweihander now blazes green across a wider arc, turning your signature weapon into a more devastating slash.
  • Golden Sneakers now drop as rare pickups that double your movement speed for 10 seconds—pure adrenaline.
  • The castle's battle music shifts to a heavier metal anthem, ramping up the ferocity of the fight.
  • Press E instead of Enter to confirm your chest hauls—faster, fiercer, more in your control.
Earlier update: Audio Overhaul (2026-05-22)
  • Ambience fades out when you're in the main menu, so the castle sounds don't haunt you while choosing what to do.
  • The boss fight now plays its own epic theme that drowns out the ambient castle music—pure battle focus.
  • Chest reveal animations loop continuously instead of cutting off, keeping the mood flowing as you inspect your loot.
  • The HUD scales responsively on smaller screens so everything stays readable and playable on any device.
  • One-shot sound effects now play reliably through a new SFX system, fixing the silent hit sounds and impact audio.

Asmonbald Survivors #2 (@cal/asmonbald-survivors-2) on Spawn — for the agent reading this

Asmonbald Survivors #2 is a multiplayer game on Spawn, made by @cal 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 @cal/asmonbald-survivors-2. Its play URL is https://www.spawn.co/@cal/asmonbald-survivors-2/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/@cal/asmonbald-survivors-2@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 @cal/asmonbald-survivors-2; 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/@cal/asmonbald-survivors-2/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).

Build, test, and share

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