WhileAtomfallis an open game that lets you explore at your own pace, it still has a lot of features you’d expect to see from an open world action game. There are skills, multi-part quests, and lots of abilities to keep track of.

One thing you’ll get frustrated with early on in the game is the stamina system. As you run around the world, your heart rate increases until you cannot run anymore. It’s shown in the bottom right of the screen, by your health bar, and the edges of the screen go dark as you reach your max heart rate. You’ll want to increase your max heart rate as soon as you’re able to.

It’s the top left skill in that section of the menu.Unlocking that will improve your max stamina and ensure your heart rate increases at a slower rate, allowing you to run for longer without having to stop.
