Released 2026-10-04. 10 updates since release, the newest 2026-10-07.
Newest update: Garage Button (2026-10-07)
- New garage button on the HUD, top right, just left of the leaderboard trophy. One click opens your garage, so you never have to remember G (still works too).
Earlier update: Mobile Trick Controls (2026-10-04)
- Easier spins and flips on phones:
- Two quick flicks on the right stick now start a fast spin or flip with a lighter push and a wider timing window.
- Only the direction you're mainly pushing counts, so a diagonal thumb won't mix things up.
- Push the stick all the way to the edge to go straight into a fast spin or flip; a lighter push still leans slowly for whips.
- Keyboard controls haven't changed.
Earlier update: Mobile UI Optimization (2026-10-04)
- Phone layout cleanup:
- Jump pre-load meter is smaller and sits right of the speedo, clear of the left stick.
- Engine noise toggle is a compact tile under the leaderboard, race and trick attack buttons.
- Those three buttons are smaller and moved in, clear of Spawn's sidebar.
- Reset, home and garage sit in the top-left corner.
- TRICK and POP moved right, above the XP bar, easier to reach with your thumb.
Earlier update: Event HUD for Racers Only (2026-10-04)
- Race and Trick Attack status bars, leaders and results boards now only show for the riders in that event. Everyone else still sees the call to join while it's open.
Earlier update: Crew Streaks + Online Riders (2026-10-04)
- Crew XP now scales: every race or Trick Attack in a row with any of the same riders adds +25% to the crew bonus, up to double.
- Online riders: the leaderboard shows a green dot next to every rider who's on right now.
- Live player beacons: a light column stands over every other real rider so you can find each other. You never see your own, and a beacon shrinks to a small marker when that rider is close.

@chizkeykkk · loved it · 2026-10-04 · played 12 min: “The tutorial was so helpful! 😂 Tho, I know this is a skill issue because I can’t get past it lol. I love the controls they’re easy to understand, and the tricks are so cool!”
- @doctordripp (maker) replied 2026-10-05: “Whips are a little tricky. Hold spacebar and let go as you go off a jump, then press both directional controls in the same direction, then let go. it will make you whip your bike to the side like an irl whip”
@flickaboo · loved it · 2026-10-04 · played 13 min: “Really love this game! The tutorial helped a lot with getting started, and I like that you can freely roam around, perform stunts, and earn money to upgrade your bikes. It makes exploring and practicing really enjoyable.”
@makeriffic · loved it · 2026-10-04 · played 41 min: “I now love dirt bikes!! I like how the game emphasizes the actual physics of the riding a bike. I really love that I could control the body weight and shift it the way I want to ride better and do trick smoother,”

HARDPACK (@doctordripp/hardpack) on Spawn — for the agent reading this
HARDPACK is a multiplayer game on Spawn, made by @doctordripp 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 @doctordripp/hardpack. Its play URL is https://www.spawn.co/@doctordripp/hardpack.
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/@doctordripp/hardpack@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 @doctordripp/hardpack; 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/@doctordripp/hardpack.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/@doctordripp/hardpack/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @doctordripp/hardpack 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).
Build, test, and share
Publish when the game is ready for players. Share its play link so friends can join.
