Subnautica is an underwater survival game developed by Unknown Worlds Entertainment, first released in early access in 2014 and fully launched in 2018. The scanner is one of the player's core tools, used to scan flora, fauna, and technology to unlock database entries and blueprints. Clips of its distinctive beeping scan have been reused in edits and memes far beyond gameplay videos, usually as a joke about analysing people, objects, or situations in detail, which keeps the sound recognisable even to viewers who have never played.
