IF - Underfell

In "IF - Underfell," players control a customizable Frisk who has fallen into Mt. Ebott, home to a kingdom of banished monsters who resent and distrust humans. With no way to climb back out, players must move forward and navigate through the Underfell, a darker version of the original Undertale game. This alternate universe is set in a world where humans and monsters were once at war, leading to the sealing of monsters underground by a magic spell.
