DN1: Mary

## Information and Basic Mechanics shared between versions

Mary is the main and most dangerous enemy in the game. As seen via the picture to the right, Mary takes on the appearance of a heavily charred mummy, with bare-bones arms and legs able to be shown.

She wanders, searching out the player as she roams the halls. Once she finds the player, she will give a few variable noises, namely an earsplitting scream or a shriek. Given that Mary has spotted the player, a screechy, repetitive metallic sound plays as background "music", her screams still able to be heard when not too distant from her. Once these sounds fade, it means she has lost the player. While giving chase, she is walking at about the same speed as when the player walks, so it is quite easy to lose her when running. However, this can change under certain circumstances.

She can be found either wandering in the hallways, or idling in a room, waiting for the player to bump into her. She cannot see the player from afar and neither can she be seen by the player from a long distance. However, when she is facing the player, she can see them from a longer distance given they have a lit candle. While in a chase, the player can slow her movement by closing doors behind them. When the background music stops playing, she will still "track" the player until she has lost interest, although she may reach the door of the chamber the player is hiding in prior to this.

The game initially makes players believe that Mary is always somewhere in the map, wandering, seeking the player, but this is in fact not the case. Some tips in the loading screen, or notes found give the player hints about the true mechanics of Mary. Examples:

"Day 6: Something saw me and chased me into this room... It went away after I closed the door"

"Day 14: I found Mary in a room today... She wasn't there earlier"

As these hints imply, Mary actually spawns, disappears and respawns at different specific points, more specifically, chambers. Just after the game starts, Mary is nowhere in the map. The time it takes from the beginning of gameplay until Mary spawns somewhere depends on the night. The more advanced the night, the sooner she will spawn. She usually spawns in chambers close to the player's location and waits there, or opens the door and starts wandering in the hallways, opening doors while doing so. When she spawns and is really close, she will sometimes come towards the player's location (“Keep running, they know where you are”). When Mary is nearby, BGM stops and only the heartbeat can be heard. When close to a corpse, a fly can also be heard, sometimes covering the absence of BGM. If she never finds the player, after some time, she will disappear and BGM will start playing again. If you encounter an open door, but BGM is still playing, this means that at some point, Mary spawned there and she opened that door, but she never found you. Progressing to the next nights, the frequency at which she spawns increases. She also tends to spawn even closer to the player's location. In Night 7, it is possible to run into her in under 30 seconds after starting the game. It is also possible to run into her without BGM dying down, because the BGM doesn’t stop immediately and it needs some seconds until it stops completely.

## ORIGINAL: Specific mechanics

While in a chase, if the player fails to escape Mary for too long, the next time she gets close to them, she will throw a low frequency roar (almost like a man, or monster screaming) and start running non-stop. If this happens, it is very difficult to escape her, as she moves fast enough to pass through a closing door before it closes completely. This will almost always result in defeat, especially in the last 3 nights, where she cannot be stunned by taking advantage of the first hit to the player (read below).

In Nights 1, 2, 3 and 4, she has to harm the player twice for the game to be lost. In Nights 5, 6 or 7, she can kill the player with one hit. This means that in the first 4 Nights, there is hope for the player to escape her even if she is already running. Once she harms the player she gets stunned for a little while, enough to close a door nearby and successfully block her route. But it is impossible in the last 3 nights.

## REMASTERED: Specific mechanics

Some of Mary's mechanics differ from the original game. She seems to follow a different algorithm to follow the player. In the original game, Mary always follows the path the player makes on the map, whereas in this version, she is aware of the player's exact location on the map. She frequently uses shortcuts to catch up to the player and she even gets stuck in a corner, trying to get to the player via a straight line, when that is not possible by a little. This sometimes leads to surprise attacks, because there might be a shortcut not yet discovered by the player. She also doesn't seem to be able to run. However, she can freely clip through objects like tables and barrels and even the Exit.
