Undertale, released in 2015, is an indie role-playing game known for its turn-based battles, where attacks are timed and dodged rather than chosen from a menu alone. The hit sound comes from those battle sequences and became familiar to players through repeated encounters with enemies across the Underground. As clips and playthroughs spread on video platforms, editors lifted the short impact for memes and fan edits, where its recognisable game feel instantly signals a hit. It remains popular because it is brief, clear and closely tied to one of the most replayed indie games of its era.
