Released 2026-10-21. 3 updates since release, the newest 2026-10-22.

Newest update: Ворн и Пепел / Vorn of Ash (2026-10-22)
  • НОВЫЙ ГЕРОЙ ВОРН, маг пепла: угли, слепящее облако, рывок и ульта «Пепельный смерч». Надменный и грубый. / NEW HERO VORN, the ash mage: embers, a blinding cloud, a dash and the Ash Storm ult. Arrogant and rude.
  • Окно героя на весь экран: каждый маг выходит на фоне своей стихии и хвастается силой, полная история, сильные и слабые стороны. / Full-screen hero window: each mage stands in their own element, boasts of their power, with full story, strengths and weaknesses.
  • Эмоции на G: насмешка, хохот, победа, УВАЖЕНИЕ и 4 танца со своей музыкой, у каждого героя свои реплики на русском и английском. / G emotes: taunt, laugh, victory, RESPECT and 4 dances with their own music, every hero with their own lines in Russian and English.
  • После матча арена остаётся перед глазами: станцуй над побеждённым или поклонись достойному сопернику. Нокта и Ворн заговорили в бою. / After a match the arena stays up: dance over the beaten or bow to a worthy rival. Nokta and Vorn now speak in battle.
  • Игра работает плавнее, звуки боя больше не слышны в штабе. Исправлено: урон от своей ульты, выбор Нокты, мышь в колесе эмоций. / Smoother game, battle sounds no longer reach the HQ. Fixed: self-damage from your own ult, picking Nokta, mouse in the emote wheel.
Earlier update: Нокта, маг теней (2026-10-22)
  • New hero Nokta, shadow mage: black smoke, soul drain, Circle of Darkness swamp and a clan of shadow spirits. Fixes from your reviews: your own ult can no longer hurt you, the climbing animation on ramps is gone, ults charge for 30 s at match start. The experimental MOBA arena is removed, so the lobby runs lighter.
What players say
  • @yujiro · loved it · 2026-10-22 · played 6 min: “I had a blast playing this fast-paced game. Dropping my ultimate on a group of enemies felt so satisfying, and I really liked being able to steal their life points to keep myself alive during fights.”

    • @steppeprotocol (maker) replied 2026-10-22: “Thank you so much! That soul drain is Nokta's, our new shadow mage, so it's great to hear it keeps you alive in a fight. A big ult landing on a whole group is exactly the moment we build for. More heroes and dances are coming soon. See you in the arena!”
  • @neitantei · needs work · 2026-10-21 · played 5 min: “I'm really enjoying your game! Just noticed a few things that might need some fixing: you can get hit by your own ult, the character plays a fence-climbing animation when jumping on a ramp, and an ult is already ready at the start. Hope this helps!”

    • @steppeprotocol (maker) replied 2026-10-22: “Thank you so much, this really helps! All three are fixed: your own ult can't hurt you anymore, the climbing animation is gone, and ults now charge for 30 seconds at the start of a match. Also meet our new hero Nokta, a shadow mage. Hope to see you in the arena!”
  • @chizkeykkk · needs work · 2026-10-21 · played 6 min: “I get confused about who's my enemy and who's my ally. The skills are okay, but the visuals could be cooler! Overall, this game has potential. Hope you keep improving it, and thanks for adding English!”

    • @steppeprotocol (maker) replied 2026-10-21: “Thanks so much for playing and for the honest feedback! You were right about allies vs enemies, so the next update adds a red arrow and red outline over every enemy, a blue diamond over allies, and a health bar on each. The visuals got a big pass too: bright daytime arenas, punchier hits, kill bursts, and the heroes now talk in battle. More heroes are on the way. See you in the arena!”
  • @makeriffic · loved it · 2026-10-21 · played 11 min: “This somehow looks like mobile legends bang bang. I love the lightning strike of the male's ultimate, it's so far and so deadly at the same time. His Storm stream is just short range but packs a lot of damage too. I hope more heroes are added more.”

    • @steppeprotocol (maker) replied 2026-10-21: “Thank you, that means a lot! The lightning ult is one of our favorites too, glad it feels as deadly as it looks. Storm stream is meant to be the up-close punish, so you read it right. New heroes are already in the works, and the heroes now speak in battle, with lines on entry, ult, kills and death. Come back and try them soon!”

Empire Arena (@steppeprotocol/empire-arena) on Spawn — for the agent reading this

Empire Arena is a multiplayer game on Spawn, made by @steppeprotocol 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 @steppeprotocol/empire-arena. Its play URL is https://www.spawn.co/@steppeprotocol/empire-arena.

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/@steppeprotocol/empire-arena@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 @steppeprotocol/empire-arena; 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/@steppeprotocol/empire-arena.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/@steppeprotocol/empire-arena/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @steppeprotocol/empire-arena 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).
