How hard is Undertale?
Where the challenge is: execution — reflexes, timing and precision. You get through it by getting better at playing it — dodges, parries, muscle memory — not by turning up with a smarter build.
Finishing it
Undertale has an ending, but nothing in its achievement list marks it clearly enough to trust — so there's no finish rate to show.

About Undertale
A small child falls into the Underground, where monsters have long been banished by humans and are hunting every human that they find. The player controls the child as they try to make it back to the Surface through hostile environments, all the while engaging with a turn-based combat system with puzzle-solving and bullet hell elements, as well as other unconventional game mechanics.
How rarity is calculated
Each platform calculates rarity from its own player population. These percentages are shown side by side but are not a controlled comparison.
- PlayStation — Sony's published earn rate across PlayStation Network players.
Percentages are shown exactly as each platform publishes them. Pyroblast does not recalculate them and does not mix player populations together. Data updated .
