Unknown Specimen 1 (A.K.A. White Face) is an enemy that can be randomly encountered in the Endless Mode.
Unknown Specimen 1 is a floating, white pixelated face. The face has empty eye sockets, uneven teeth, and is lacking a nose.
Before it attacks, rooms will turn pixelated and a loud, ominous piano tune will play to warn the player before it arrives. After a few more rooms the chase will begin.
A static noise will play if the player character is close to Unknown Specimen 1. Looking at White Face will make it teleport away to a different location while the screen flashes red.
Unknown Specimen 1 does about 1/6 of damage to the Protagonist upon contact. It goes through walls and any obstacles. Using the Axe has no effect.
During the chase rooms may eventually start looping, preventing the room number from going up. This will make the chase longer, but eventually, White Face will leave, allowing the player to proceed.
When the Protagonist is killed by Unknown Specimen 1, the death screen flashes with the words "DEATH IS NO ESCAPE" for a few seconds. The view then shifts to a dark room with only White Face and a hanged up corpse in a sack that will have your system name as text. When Unknown Specimen 1 comes closer, it says the following sentences:
"Look at you. . .
Your body is all closed up."
The game will ask the player to confirm the word CLOSE, or to type something else. If the player types a name, the game will close automatically. However, typing Open will show the corpse's guts ripped out and start the second chase.
During this chase, the walls are red, Unknown Specimen 1 will become bigger and start floating towards the Protagonist like most other specimens. During this chase, it cannot go through walls. The player character's health is kept on 1 and if Unknown Specimen 1 damages them, the game will close. Escaping Unknown Specimen 1 during this chase will put the player back in the normal rooms and their health will start regenerating immediately.

- Unknown Specimen 1 is called White Face and comes from the Imscared games, pixelated horror games made by Ivan Zanotti.
- It is the only specimen who breaks the 4th wall.
- When the Protagonist gets killed by Unknown Specimen 1, Spooky's flashing face in the main menu is temporarily replaced with White Face until the game is restarted.
- White Face was added to the game due to Psychobilly and Akuma Kira's love for the game Imscared.
- Unknown Specimen 1, along with Unknown Specimen 5, are the only specimens who can temporarily stop the Room counter from going up during a chase.
- Unknown Specimen 1 is, so far, the only specimen with a "second chance" chase mechanic.
- Unknown Specimen 1 moves a little faster than the player's walking speed at its top speed.
- Unknown Specimen 1 has quite a few direct references to the Imscared game and its remake:
- Its starting sound is very similar to the track playing in the "Not to see" room from Imscared.
- The breathing sounds playing in the later portion of this track are also reminiscent of similar breathing sounds found in the Market area of the game.
- The mechanic of White Face's chase alongside the static sound it produces is similar to several of White Face's chases in the original game, where a similar static sound will get louder and louder as White Face gets closer to the player.
- White Face's game over screen is similar to a scene where White Face teleports the player to a pitch-black room with a noose, with the phantom slowly approaching the player while talking to them.
- The second chase room is reminiscent of the flesh room where the Heart is usually located in Imscared.
- White Face prompting the player to type in something is a nod to the original game, where White Face regularly asked the player to type in White Face's name.
White Face does not use its "realistic" face anymore in its regular chase. It will only use it in its second chase.
White Face is considerably slower and no longer teleports when looked at. Instead, it will teleport after a fixed amount of time. It seems to have a higher chance of teleporting right into the exit door than anywhere else. It now gradually gains speed, starting at a crawl, but soon speeding up to be faster than the player. This speed will reset each time White Face teleports. The rooms change toward the end of the chase into long, similar hallways. If multiple copies of this specimen are spawned, its static overlays stack on top of each other, potentially rendering the player nearly blind.
White Face's death screen has a few visual changes, such as White Face approaching the player in several small jumps instead of smoothly and a keyboard appearing on the screen, where the player will choose a letter by dragging the cursor over it. In its second chase, White Face is now much slower, giving the player a better chance at escaping it.
- The rooms in the second part of White Face's normal chase appears to be at least partially based on rooms from the original games that don't appear anymore in regular chases in the HD version.
