The player can find the room under the first collapsed bridge. The first Glitching Remain appears in a secret room with a shovel sticking out of a shallow grave. Collecting all of them would give the player a secret ending. There are a total of 18 Glitching Remains. They appear as collectibles that the player can gather to obtain an achievement. Glitching Remains are scattered throughout the Pale City in the game.
When Mono approaches the Glitching Remains, they disappear and Mono bends over with his body briefly turning to static. They look like young boys, dressed in pants with torn suspenders, and a shirt.
Glitching Remains appear to be composed of interference, which is likely harmful signals from the Transmission.
