About this game
Game Summary Decay is an incremental game in which you are tasked with using your trusty particle launcher (which may or may not have been found in a dumpster out back of the laboratory) to create ever-larger and more unstable atomic nuclei, witnessing longer and more complex atomic decay chains and aiming to discover all the isotopes! Configure your particle launcher with the right number of protons and neutrons, then hit launch to see your particle. Earn money for successful experiments, and spend that money on additional upgrades to earn even more money. Earn, spend, earn, spend, earn spend...you know how it works by now. Gameplay Features LAUNCH PARTICLES - Create your concoction of protons and neutrons to forge atomic nuclei in your (very scientific) question to discover new and ever more unstable nuclei. UPGRADE YOUR LAB - Unlock a wide range of upgrades to improve your laboratory and expand your capabilities. AUTOMATE AND EXPAND - Build additional test chambers and set them to automate multiple experiments in parallel. DISCOVER RARE ISOTOPES - With hundreds of isotopes available to be discovered, can you find all the combinations? OBSERVE REAL SCIENCE - Study the real decay chains of atomic nuclei. Do you, like all very normal people, have a favourite isotope? See how it is formed, and how it might decay! Additional Information BUY ONCE, PLAY FOREVER - We at Racctuality are committed to a policy that ensures those purchase our games are entitled to any future updates, never locking future gameplay content behind a paywall for a game you have already purchased. So long as the choice is ours to make, paid gameplay DLC will never exist for our games. (The only exception to this rule will be if ever we release purely non-gameplay content, for example concept art or a soundtrack.)
