Darkest Nightmare: Discord of the Dying is a 2018 free-to-play casual horror game developed by Popsicle Games for the iOS and Android. The game uses a monochromatic presentation, similar to Popsicle Games' previous horror game Darkest Light. The game is no longer available on official platforms.

Darkest Nightmare was presented by Popsicle Games at the Electronic Sports and Gaming Summit 2017 convention.

The player attacks enemies by drawing a series of runes, which are simple line shapes, in the touch device.
