Overview

Decay is an incremental simulation game developed and published by Racctuality. Players are tasked with operating a particle launcher to create increasingly complex and unstable atomic nuclei. The core loop involves launching particles, earning currency for successful experiments, and reinvesting that currency into upgrades to enhance particle generation and earn more money. The ultimate goal is to discover all the isotopes through intricate atomic decay chains.

Highlights

  • Incremental Science Simulation: Configure your particle launcher with protons and neutrons to build atomic nuclei and observe their decay.
  • Automation and Progression: Earn money from experiments to purchase upgrades, automating and accelerating your progress.
  • Discovery and Collection: Aim to discover all possible isotopes by witnessing longer and more complex atomic decay chains.
