ASCENT

Earlier update: The Notice (2026-08-05)

• A new notice strip appears at the top of the menu — dismiss it once and it stays gone for your session.
• UI text now renders with a serif typeface, giving the interface a more deliberate, carved-in-stone appearance.
• Settings sliders have been refined with clearer visual feedback and more responsive interaction.

Earlier update: The Rim Reckoning (2026-08-05)

• Knockback is now tighter and more controlled — you won't get launched as far across the arena.
• Falls off the rim now properly drop you into the moat instead of the void — the difference between fire and nothing actually matters.
• Getting shoved near the edge is no longer a guaranteed catapult; close to the rim, outward knockback gets capped so you can fight your footing instead of flying.

Earlier update: First Blood (2026-08-04)

• The psi-brains are back with their plasma halos — they vanish if your frame rate drops too low, so the arena keeps running smooth.
• Grenade projectiles now travel faster and bloom bigger, making the launcher feel more aggressive and punchy in a fight.
• Health and armour pickups flash your screen with colour when you grab them — pink for health, yellow-green for armour.
• A bug where the Maw wouldn't appear on wave 5 after a death is fixed — it now shows up every time.
• The bestiary window no longer gets stuck on you mid-combat if you reload mid-fight.

Earlier update: The Specimen Update (2026-08-04)

• You can now study every monster in the bestiary—inspect their bodies in a specimen viewer, watch them rotate on a turntable, and frame them up close to learn their shape and size before you face them.
• Enemies that wade through the lava burn alive—their heads wreathed in flame—and die to red mist instead of vanishing, leaving their death written on the sand.
• The moat's ancient burn now shows in the stone itself: scorched bands ring the lava lip with slag and salt crust, heat-cracked spall along the deck edge, a decade of melt written into the masonry.
• The crowd bowl is gone—the arena's backdrop of spectators has been cleared, opening the view and sharpening the frame.
• Enemies shoot you less often when they're behind you, and the forcefield hits harder when you touch it.

Earlier update: The Balance Pass (2026-08-02)

• Enemies no longer gang up on you when you're out of view — they'll shoot you off-camera, but they won't coordinate a massacre from behind your back.
• The Maw is now three times bigger and hits harder to match its new size, making its charge a genuine threat instead of a glancing blow.
• Gladiators and Heavies hit less hard on melee but shove you much farther — they're bullies, not assassins.
• Psi-Brains fire half as often but only when they can see you, so their bolts feel like a fair fight instead of punishment.
• Performance improved: distant decorations and lava effects now cull at range, letting your frame rate breathe during big arena moments.

Join and play, by yourself

This world is @ejthebae/ascent. Its play URL is https://www.spawn.co/@ejthebae/ascent/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/@ejthebae/ascent@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 @ejthebae/ascent; 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/@ejthebae/ascent/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.
