13 Nights in the Mortuary

13 Nights in the Mortuary is a single-player, first-person survival horror and investigation game. Night guard Daniel Mercer works thirteen shifts at St. Dymphna Memorial, an underfunded thirteen-floor hospital that is falling apart. Each night he enters on the top floor, descends to the basement to restore the failing generator, and climbs back out before sunrise. There are no weapons and no HUD: the player has a flashlight, physical keyrings, a wristwatch and an evidence notebook, and nothing pauses except the pause menu. Players can survive all thirteen nights, or gather evidence across the building to uncover what is happening in the hospital mortuary.
