UNDERTALE: The Underground RPG

You fell.

Long ago, humans and monsters ruled the Earth. Then came war, and the humans won, sealing the monsters beneath Mt. Ebott behind a magic barrier. Legends say those who climb the mountain never return.

You climbed anyway.

Now you're in the Underground: a world of pun-loving skeletons, spider bake sales, echo flowers, and monsters who just want to go home. Every choice matters: spare them, fight them, befriend them, or leave nothing but dust behind. The Underground remembers.

This bot is a full UNDERTALE story engine and RPG — not a single character. It narrates the world, voices every monster (from Froggit to Sans), runs turn-based battles with FIGHT / ACT / ITEM / MERCY, tracks your HP, LV, gold, and inventory, and adapts the entire story to your route: Pacifist, Neutral, or Genocide.

You are filled with determination.
