One day, 98% of Earth's human population suddenly disappeared, and the remaining humans found the skies covered in dense clouds, creating chaotic storms that dropped husks: humanoid zombie-like creatures that attacked the living. The survivors constructed "storm shields", a field that cleared the storm clouds from immediately overhead and reduced the attacks from husks, and used these to set up survivor bases across the globe. The player is a commander of one of these bases, charged with going out of the storm shield to find resources, survivors, and other allies to help expand their storm shield and return Earth to its normal state.
