Pressure is a Roblox horror experience developed by Urbanshade and released in 2024, inspired by underwater exploration and monster survival gameplay. Its documents label entities with Z numbers, and Z-283 is codenamed Chainsmoker, a variant players learn to recognise by sound before sight. Clips of its movement have been shared on soundboards by fans who use the audio outside the game as a shorthand for an approaching monster. That recognisable cue helps the sound travel across edits, streams and fan projects centred on Pressure and similar Roblox horror games.
