How the world simulation works

Atomcraft’s main challenge is managing fully simulated pixels and reactions while turning raw materials into useful tools and machine inputs.

  • Every pixel mattersYou can pick up and place each pixel, and nearby conditions influence behavior and reaction outcomes.
  • 118-element chemistryGameplay revolves around finding, extracting, and processing all elements across the planet’s layers.
  • Reaction safetyAdvanced materials can be unstable, so controlled machine setups are important for reliable crafting.
