Dormont appears to be a regular and typical American town at first glance, but it is however cursed by a demon who shrouded everything in darkness. Most of the town's population has been trapped inside the darkness, with no means of escape.

Edward Turner is just an ordinary man with a troubled past, who arrives in the wrong place at the wrong time. He soon finds out that something is very wrong in Dormont. There are strange creatures roaming in the dark, killing everyone that gets close. The only way to survive is by staying in the light.

The biggest threat in Those Who Remain is ethereal: the darkness. The monsters roam free in the dark, and the player will die if he stays there for too long. The threat is always there, waiting on the edge of the light and darkness. Sometimes the lights will fail, forcing the player to run. He will have to find light sources to proceed through dark paths. But there are also other threats: physical monsters that move freely in both the light and the darkness.

Those Who Remain was originally planned for Q4 2018 (with a Switch version to follow in 2019), but since that obviously did not happen, developer Camel 101 confirmed that the game is now scheduled for 2019 across all platforms.

The danger in the dark is not the only thing at play in Dormont.

The other main mechanic of the game is the “mirror worlds”. While the player progresses through the adventure, he finds strange portals that emanate a bright light, will bring him to a very similar yet different area, apparently unreal but very real, like a mirrored version of the real world

Actions taken in one place have repercussions in the other. , so sometimes the player needs to travel between both to solve puzzles.

Those Who Remain will be available for PC, PS4, Xbox One, and Nintendo Switch, in 2019
