Description
Undertale is a captivating, story-driven RPG with retro-inspired graphics and a deep choice-based system. Long ago, the world was shared by two factions: humans and monsters. A fierce war eventually erupted, crowning humanity as the victor, and mankind gradually forgot all about their subterranean neighbors. Everything changes when a curious youngster exploring a mountain cave falls into a deep chasm, landing directly in the underworld where the defeated monsters were banished. Now trapped underground, the protagonist must set out on a thrilling and perilous adventure where critical choices will shape every encounter along the way.
