Dark Hours: Prologue is a free version of Dark Hours, framing its horror around a robbery gone wrong. Players enter an auction house to steal valuable items, but a supernatural event traps them inside with a demonic creature. The heist remains part of the survival problem: carrying more loot makes players noisier, increasing the danger of attracting the monster.
Exploration combines escape efforts with practical tasks. Players search for a way out, solve cooperative minigames, deactivate lasers and security cameras, and use the building’s secrets. Equipment such as a lock-picking set, hacking device, flashlight, or crowbar supports the group’s efforts, while the prologue describes up to two creatures with distinct behaviors and abilities. Its defining tension comes from balancing the urge to steal against the need to stay quiet and survive.
The game is designed as a cooperative horror experience for one to four players, with the store listing both single-player and online co-op categories. The stated ways out are finding the exit or hiding from the creature until morning.
