List of Easter Eggs[]
Uboa[]
Nightmare House 2 Uboa

Uboa comes from a 2005 adventure game named Yume Nikki. In one particular area of the game, before murdering a girl named Poniko, there is a remote chance that after turning off the lights in a room, Uboa will appear. Uboa is mostly known for his disturbing, contorted face and the heart-pounding music accompanying Uboa's appearance. This character holds a nightmarish grasp on many players' hearts due to Uboa's sudden and unpredictable appearance. Many who discovered him by pure accident were scared out of their minds. Uboa serves as an easter egg in Nightmare House 2 in Chapter 4 while confronting the Shadows.
During Chapter 4, the Patient finds himself in a hallway where several Shadows will appear. At the end of this hall, the Patient may stumble upon an empty room with a button that seems to do nothing. If the Patient repeatedly presses said button, Uboa will eventually appear in the center of the room with an unnerving music track playing in the background. If the Patient gets too close to Uboa, he will be teleported outside of the room, and the door will be locked.
In the 2015 version of Nightmare House 2, the Uboa easter egg is removed, as well as the room it is found in.
Weegee[]
NightMare House 2 WTF??? Luigi?

Weegee is the odd version of Luigi. He has a brother named Malleo who is the odd version of Luigi's brother, Mario. Weegee has the ability to hypnotize people when he makes eye contact with them and eventually starts a Weegee virus. This virus makes other individuals have the same exact face as Weegee. Weegee is best known for his creepy stare and is arguably one of the most creepiest characters of the Mario series, despite being a meme and not an actual character licensed by Nintendo. Weegee serves as an easter egg in Nightmare House 2 in Chapter 2 in the radiology department.
While in Chapter 2 of the game, the Patient finds himself wandering around the radiology department. If he goes into the first door on his left, he will find a room with a recycling bin in the corner. If the Patient moves the recycling bin aside, he will find Weegee in the corner gazing at him continuously.
In the 2015 version of Nightmare House 2, the Weegee easter egg is removed.
Thumbs Up[]
This easter egg can be found at the start of Chapter 2, right after getting out of the elevator. The player needs to turn around and jump back into the elevator shaft, landing on a horizontal steel beam that's level with the floor. At the end of the beam, in a small depression in the wall, and inside there's a picture of a person giving a thumbs up.

4_1_22_5[]
In the 2015 version of Nightmare House 2, a map named "4_1_22_5" is located in the game files. If loaded via the console, the player is immediately kicked out of the map and into the main menu. In order to access the map, the player must do so in Chapter 5. After the area where the mannequins first start haunting the Patient and after being forced to turn around due to locked double doors, there is a large, dark room with tables and mannequins. All mannequins in the room must be knocked over onto the ground. After doing so, a hole will appear in a wall in the room, leading to a level change into "4_1_22_5". The map can then be played from there.

The map is set in what appears to be an old, abandoned house. It is centered around the mannequins and the Patient is constantly haunted by them in it. The Patient will frequently hear a man's voice repeating certain phrases as he progresses through the map, though the man is never seen. There are no enemies to fight and the map is fairly linear. The Patient will appear back in the large room (with all the tables missing and waking up surrounded by mannequins) in the hospital after reaching the end of the level. The hole in the wall will be gone and cannot be accessed again in the same playthrough.
The True Ending[]
The True Ending is an Easter egg in Nightmare House 2 which can be found by typing "map this_is_not_an_easter_egg" into the console. It is considered to be the actual ending to the game and reveals what happens to the player after the original ending found within the game.
In the 2015 version of Nightmare House 2, the map is removed.
