Sleepless is a multiplayer horror game inspired by the myth 'The Russian Sleep Experiment.' The game is set in a bunker in present-day Russia. The players' goal is to collect all the evidence items from the bunker that can provide important information about the past experiments. However, this is not an easy task, as the abandoned bunker is difficult to navigate, lack of electricity, and the constant feeling of being watched by the blind experiment victim. Distract the monster: Find objects in the bunker and use them to create sounds, diverting the attention of the blind monster. Collect Evidence: Gather randomly placed evidence throughout the bunker to win the game. Be cautious, as finding evidence will gradually increase the monster's aggression. Control the Gas: Manipulate the gas switches, which are operational only when the generator is powered, to safely navigate through different rooms.
