There are a surprising number of Atomfall endings for what is a relatively small game, but as you explore the Windscale quarantine zone, you'll find plenty of characters who are willing to help you escape. That is, if you complete a series of tasks for them, or in some cases, even sell your soul. After all, the secrets of Oberon are valuable and many hope to salvage them before shit goes sideways.
There are certain steps you'll have to complete to access any ending, which I'll explain below, but besides that, I'll walk you through the steps to get each of Atomfall's five endings. There are also a few minor ending variations, such as how bloody you got exploring the quarantine zone, but considering how often you have to kill folks, it'd be surprising if you managed to achieve anything but the worst there.
