Released 2026-11-12. 6 updates since release, the newest 2026-11-13.
Earlier update: Gunpowder, copper and tape (2026-11-13)
- From run 6 the loot brings a new material each run: gunpowder, copper, duct tape. After run 8 build the reloading press (faster bullets), the mine crate (2 mines on the street each run) and the copper jig (rounds pierce 2 bodies). Also: runners from run 10, a new guitar theme, a top-left menu with START NEW and a concept-art wiki.
Earlier update: The Workbench (2026-11-12)
- New players meet Vincent first: a quick lesson shows how to pull back and shoot
- Crafting now happens at a big workbench out back of the cabin, in the mist
- Every good hammer hit kicks up sawdust
- The cabin's fence and undergrowth now run to the edges of the screen
- The left arrow in the CRAFT menu now goes back

@flickaboo · loved it · 2026-11-14 · played 5 min: “An old man with a sniper is no joke! 😂 Had fun defending the rooftop and taking down infected. The survival and looting mechanics were easy to understand!”
@lego · 2026-11-12 · played 6 min: “Uuuhh I don't think the controls are working, dude. Haha @videogamenews”
- @op_nico_main (maker) replied 2026-11-12: “Hey man thanks so much, I was optimizing for mobile only, please try now! Drag mouse backwards from vincent. Adding a tutorial as we speak. Let me know especially how hitting the infected feels, since that is my main biggest feature I am proud of haha”

Man vs Many (@op_nico_main/man-vs-many) on Spawn — for the agent reading this
Man vs Many is a multiplayer game on Spawn, made by @op_nico_main 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 @op_nico_main/man-vs-many. Its play URL is https://www.spawn.co/@op_nico_main/man-vs-many.
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, and a person's browser plays it with no sign-in. https://www.spawn.co/@op_nico_main/man-vs-many@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.
A browser a script drives, headless or not, plays signed in as your account: POST https://www.spawn.co/api/agent/v1/login-link with {"next":"/@op_nico_main/man-vs-many@dev"} answers a one-use URL that signs that browser in.
Unsigned, such a browser is a guest, and a creator's world refuses it: "this browser was opened by an automated tool, so it can't visit a creator's world as a guest. sign in, or open the link in a browser you use yourself." Its maker can ask Spawn to let their own automated tool in by name.
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 @op_nico_main/man-vs-many; 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/@op_nico_main/man-vs-many.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/@op_nico_main/man-vs-many/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @op_nico_main/man-vs-many 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, 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).
