Undertale is a role-playing game created by Toby Fox and released in 2015. A human child falls into the Underground, a world beneath a mountain where monsters have lived since a war long ago. To return to the surface, the child must cross the Underground and meet its many strange, funny and sometimes sad inhabitants. The unusual idea is that you never have to kill anyone. Every enemy can be spared through conversation and understanding, and the game remembers how you treated each character. Toby Fox wrote, designed and composed most of the game himself, and its music became very popular. Undertale is loved for its humour, surprises and emotional moments.

Our verdict

Undertale asks a simple question: what if you did not have to hurt anyone in a role-playing game? The answer leads to a story that is funny, kind and surprising. Its characters are memorable, its music is outstanding, and its battles turn into small puzzles about understanding others. It is short enough to finish in a few evenings but has secrets that reward replaying.

  • What works

  • A unique battle system built around mercy.
  • Memorable characters and excellent music.
  • Choices that truly change the story.
  • What does not

  • Simple graphics may not appeal to everyone.
  • Some boss fights are difficult for new players.

How to play Undertale

You explore the Underground from a top-down view, solve light puzzles and talk to characters. When you meet a monster, a battle starts with four choices: FIGHT, ACT, ITEM and MERCY. FIGHT attacks with a timing bar. ACT lets you interact in many ways, such as complimenting, joking or comforting; the right actions calm the monster. When a monster no longer wants to fight, its name turns yellow and you can choose MERCY to spare it. During the monster's turn, your soul appears as a small heart inside a box, and you must move it to dodge patterns of bullets and shapes, in a style similar to shooting games. Each monster has its own attack patterns and personality. The story and ending change greatly depending on whether you spare monsters, fight them or mix both approaches.

Tips for new players

  • Try different ACT options; every monster has its own way to be spared.
  • Read every line of text; jokes and hints are everywhere.
  • Avoid looking up spoilers before your first full playthrough.
  • Watch each attack pattern carefully; most have a safe path through them.
