Doors is a first-person horror game on Roblox released by LSPLASH in August 2022, built around passing through one hundred doors while avoiding different entities. Halt is one of those entities, appearing in a long blue-lit hallway where players must repeatedly turn back and move forward as the figure rushes toward them. The ambience became a recognisable shorthand online for that encounter, shared in Doors edits, fan animations and soundboards, and reused whenever creators need the specific uneasy feeling of being stalked down a corridor.
