The new horror game on the block has several mysteries to uncover, if you’re brave enough to go through that door.
The objective of the game is to reach Room 100 without dying to any Entities. They can open drawers to earn coins and find items such as lighters and lockpicks. They are able to hide inside of wardrobes and under beds to escape the monsters.
In this experience, players must maneuver throughout, and ultimately escape, a haunted hotel by sneaking, sprinting, solving puzzles, and, most importantly, evading various chilling monsters.
The Hotel is procedurally generated, with a set of predetermined rooms that appear in a different order every game that is played. Some rooms require keys to be entered, and some rooms can be dark, requiring a light source to see. There are currently a few entities/monsters in the game which each hold different mechanics.
DOORS is currently on Chapter 1 (The Hotel) and sneak peaks of a 2nd chapter can be seen.
