Tactical Pulse: Vocab Ops (Beta)
A game by @elbusano on Spawn.
Genre: Shooter
Tactical Pulse: Vocab Ops (Beta) I got tired of just multiple choice. What about multiple choice with a rifle in your hands and drones firing back? Tactical Pulse is an educational third-person shooter that trains vocabulary under pressure. Drones fly in carrying answers: shoot the right one, and miss at your own risk. Practice your way: - Word to Meaning - Meaning to Word - Fill the Blank - Synonyms - Antonyms - Mix (all five) Levels get faster with more drones, careless shooting makes the drones fire back, and an AI Coach turns your missed words into a study session in any AI chat. Built for everybody: anyone who wants a sharper vocabulary, including students heading to higher education and studying for the SAT, GRE, and more. The game is in early beta, and the goal is to keep it growing. It already has a strong corpus of words, with new words added frequently, plus more features and fixes on the way.

From the maker
Studying vocabulary always felt the same to me: read a question, pick A, B, C, or D, repeat. I wanted to see what happens when choosing the right answer takes quick reading, a steady aim, and nerve while drones close in.
Right now the game is in early beta, and this is just the starting line. I'll keep adding new words often, and more features are on the way as it grows.
Thanks for playing. If you spot something off or have an idea, let me know.

Tactical Pulse: Vocab Ops (Beta) is a multiplayer game on Spawn, made by @elbusano 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 @elbusano/tactical-pulse-vocab-ops-beta. Its play URL is https://www.spawn.co/@elbusano/tactical-pulse-vocab-ops-beta.
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/@elbusano/tactical-pulse-vocab-ops-beta@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 @elbusano/tactical-pulse-vocab-ops-beta; 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/@elbusano/tactical-pulse-vocab-ops-beta.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/@elbusano/tactical-pulse-vocab-ops-beta/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @elbusano/tactical-pulse-vocab-ops-beta 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).
