Specimen 11 is a floating, red creature with a demonic appearance. Its eyeless head bears two large horns. Specimen 11 also has long claws at the ends of its fingers and lacks clothing. Not only is its head eyeless, but it also appears to be lacking both ears, a nose, and a mouth of any kind. Specimen 11's eye sockets leak blood down its face.
Main article: Room 710
Specimen 11 floats and moves quickly. Hitting it with the axe causes it to dissapear for a few seconds, giving the Protagonist some time to escape.
Specimen 11 first appears in the freezer of Room 710, Once The Protagonist grabs the key and nears the exit, It will spawn at the freezer's door.
Specimen 11 deals 45 damage on contact. During the chase, it can make doors turn invisible, in an attempt to confuse the player. At random intervals, it will inflict the player with a variety of full-screen visual hallucinations.
When Specimen 11 kills the Protagonist, there is no initial death screen. Instead, it will teleport them to the "Meat Hallway", which is a set of non-euclidean hallways made out of red meat. At the end of the fleshy hallway, Specimen 11 appears to wait for the Protagonist. If they go back, they will end up at a dead end, forcing them to come back to Specimen 11.
If the player character comes closer to Specimen 11 in the Meat Hallway, they will be presented with the death screen, with black and white colors and reddish, flesh-like images, with the text that reads:
"With every bite with bone and skin.
The temple groaned and shook again.
His dwelling place did I neglect.
To the end with bad effect."
As this message is being displayed, it flashes a binary code:
"01000010 01100101 01101100 01101001 01100101 01110110 01100101 00100000 01101001 01101110 00100000 01000111 01101111 01100100 00101100 00100000 01100010 01110101 01110100 00100000 01110001 01110101 01100101 01110011 01110100 01101001 01101111 01101110 00100000 01110100 01101000 01100101 00100000 01110100 01100101 01100001 01100011 01101000 01101001 01101110 01100111 01110011 00100000 01101111 01100110 00100000 01101101 01100101 01101110 00101110"
Which translates to:
"Believe in God, but question the teachings of men."
It should note that hitting Specimen 11 with the axe when the Protagonist's health is already below 20% will make the specimen disappear. However, they can sometimes end up in the Meat hallway instead of the next room after going through the door, signifying their inevitable demise.
