Released 2026-10-22. 3 updates since release, the newest 2026-10-22.
Newest update: Kill Points (2026-10-22)
- Kill meter reworked: champions are 1 point, spires and siege engines ½, footmen and archers ¼, shown rounded to whole points. Kill goals rescaled to match (VS AI starts at 12, PvP is 30), overtime heals scaled up, and the tutorial explains the new values. The lobby panel now fits sideways phones.
Earlier update: Ready Up & Countdown (2026-10-22)
- The tutorial now runs with the match frozen, and the countdown only starts when you press START. PvP has a ready-up: nobody fights until every player is ready. The announcer counts 3, 2, 1, FIGHT out loud. Tutorial: BACK/NEXT buttons, the camera frames the nodes, and voice lines stop when you change pages. Finished matches leave the watch list. Close-to-victory calls no longer repeat. Leftover aim rings are cleaned up in the lobby.
Earlier update: Bigger Battles (2026-10-22)
- Ghost spires show again when you press E to place one
- PvP pads wait 12 seconds and restart the count when someone joins, so 2v2 and bigger teams can fill
- Players step straight into their match from the pads more reliably
What players say
@yzykyl · needs work · 2026-10-22 · played 8 min: “How did I lose? I played PvP against a friend as Crimson and I'm pretty sure I was winning. I captured all 3 nodes and fortified them even. If you check KDA, I killed him 3 times before dying to his final core. What did I miss?”
- @zratchet (maker) replied 2026-10-22: “I didn't have full data logged for this match but I'm working on some fixes. Please keep playing the updates and let me know how it goes.”
- @zratchet (maker) replied 2026-10-22: “I have made an update so it gives you more info on what's happening, hopefully it helps!”

Flux Formulae (@zratchet/flux-formulae) on Spawn — for the agent reading this
Flux Formulae is a multiplayer game on Spawn, made by @zratchet 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 @zratchet/flux-formulae. Its play URL is https://www.spawn.co/@zratchet/flux-formulae.
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/@zratchet/flux-formulae@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 @zratchet/flux-formulae; 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/@zratchet/flux-formulae.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.
