— Undertale's Release Trailer

Undertale (stylized as UNDERTALE and formerly UnderTale) is a computer game about a child who falls into an underworld filled with monsters. FIGHT or ACT your way through battles while dodging magic bullet attacks. Every monster has unique attacks and a unique personality—and they’re all in your way. You can show them MERCY if you want. But what will you do if you meet a relentless killer?

Undertale was released for PC on September 15th, 2015, for PlayStation 4, and PlayStation Vita on August 15th, 2017, and for Nintendo Switch on September 18, 2018.
