Atomcraft Patch Notes and Update Tracker

Atomcraft moved from demo and itch builds into a Steam full-release window in July 2026 with a rapid stream of quality-of-life and systems updates. This page summarizes the changes players ask about most — nukes, tracking, belts, map zoom, radioactivity, cooking, wiring, and performance — and links into deep guides on this wiki.

Launch-window video context

July 22, 2026 — Nuke Launcher

  • Added Nuke Launcher and nukes (highly destructive; fallout yields heavy radioactive isotopes).
  • Performance: optimized Hammer / tool highlight line drawing.
  • Rolling backups for world header savefiles (up to 5).
  • Balance: turret pixel category Ruby unlock cost reduced to 16 (from 64).
  • Balance: procgen guarantees at least one Cobaltite room in lower limestone caves.
  • F2 Editor Mode only after console command editor entry.
  • Toolbox swap safety improved to reduce save corruption.
