John Doe is a killer character in Forsaken, a Roblox asymmetrical horror game where survivors try to escape while killers hunt them down. The alarm has become a recognisable warning cue within that community, shared in edits, memes and short gameplay clips whenever John Doe closes in on a player. Its simple, phone-like ringing makes it easy to reuse outside the game too, so creators drop it into reaction videos and horror edits as a shorthand for incoming danger. That mix of game recognition and instant alarm urgency keeps it in regular use.
