One night, a night guard at Nintendo's headquarters found a blocked up room, containing suits. The suits are now after him, and he has to survive until 6 AM, when he can escape.
The gameplay is a first person game. The player can run by holding the way you go down. The player can also turn their flashlight on and off using the B button, and crawl using the A button. The player also has a limited amount of lives, at the maximum of 3 for every night. Another element in the game is the battery for your light and an energy meter for when you run. You can also take bananas and put them in places, which should keep The Donkey Kong Suit from finding you.
The Mario Suit
The Mario Suit first appears on Night 1. He drags himself across the floor, and will rip the player's face off if he catches them.
The Luigi Suit
The Luigi Suit also appears on Night 1. He walks with his left leg only, and can only sense the player through sounds.

The Donkey Kong Suit first appears on Night 2. He only goes to areas that have bananas in them, and will kill you if you are in them.
The Yoshi Suit
The Yoshi Suit first appears on Night 2. He can only sense you if your flashlight is on, and tries to eat you with his tongue.
The Wario Suit
