Ambush is one of the hostile entities in Doors, the Roblox horror game in which players move through numbered rooms while avoiding creatures that hunt them. Ambush is known for rushing back through rooms several times, giving players only a short warning before it strikes. Clips of its attacks spread through Roblox gameplay videos and short-form edits, where the sudden sound became shorthand for an unavoidable scare. It remains popular because it is instantly recognisable to Doors players and works even without any gameplay footage.
