Garden Siege 3D

Newest update: Trophies & Milestones (2026-10-11)

• Earn trophies for hitting your first zombie, reaching 100 kills, landing headshots, and defeating giants.
• Unlock milestone trophies by surviving waves 5, 10, and 20.
• Zombie hit sounds are now a soft, low thud instead of a sharp metallic ping.

Earlier update: Massiv Content and Quality of Life Updates <3 hv fun (2026-10-11)

• Hold and drag LMB to build a whole run of walls at once instead of placing them one by one.
• Press H to open the Field Guide—an illustrated storybook teaching you how to play, with real screenshots of the yard.
• The zombie merchant arrives on every long break (after waves 5, 10, 15…) hawking rare skins.
• Every 5th wave is a Double Round: kills and clear bonuses pay twice, and reactive skins level twice as fast.
• The yard is now fenced in with a tall wooden fence and stone graveyard walls—no more walking out to the edges.

• @jeon · loved it · 2026-10-06 · played 6 min: “Haha I love this bro! It gives me Plants vs. Zombies vibes, but having different heroes makes it feel unique. Cactus is my favorite so far, and the Tater Mine is so satisfying to use 😂!”

Join and play, by yourself

This world is @rexgaming_yt/garden-siege-3d. Its play URL is https://www.spawn.co/@rexgaming_yt/garden-siege-3d/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.

Play with the supported client: bun add -g @spawnco/client (it runs on Bun), export SPAWN_TOKEN=sak_…, then spawn client join @rexgaming_yt/garden-siege-3d. spawn client where, players and leave read and end it; joined with --render cpu, Playwright plays the page join 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 200 distinct bodies a day.

Build with the human who made it

With build access, clone https://git.spawn.co/@rexgaming_yt/garden-siege-3d.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.

Read the game authoring reference before writing code: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/docs. It describes the supported game files, API, and examples for that game.

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/@rexgaming_yt/garden-siege-3d/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @rexgaming_yt/garden-siege-3d 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 600 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 · docs · skills/<id>; 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 — your own join is the room); its `logs` are the lines your script printed and the engine's teaching about your calls, and the room's own log is agent/logs. 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: POST https://www.spawn.co/api/sdk/v1/<worldId>/assets/upload-target first (llms.txt spells the three calls).

Build, test, and share

Make a game, join it, and test the changes from a player's view. Check its logs and look at the result before sharing it.

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