Kill Undyne, Mettaton, Papyrus, and Toriel, and some monsters.
Kill only Undyne, Mettaton, Papyrus, and Toriel, but no monsters. Spare or killing Papyrus will result in a slightly different outcome. Killing or Sparing Mettaton will slightly affect the outcome. This causes the game to end before the additional Pacifist additions, so if you've played as Pacifist you've seen this already. Do everything required for the Pacifist ending, but kill between 1 and 9 monsters. We recommend playing Pacifist (see above) first, and then experimenting with the many different variations. There are many subtle variations to be had, but we've listed the ones with the most significant differences below, along with the effects they have.Īgain, expect spoilers below. Our Genocide run page explains in more specifics how this works.Ī Neutral playthrough is something in-between the above two endings not sparing everyone, but not quite slaughtering everything in your path, either. To get a true Genocide ending, you must kill a certain number of monsters, as well as their bosses before moving on. Doing so will see you access new content - so it's well worth playing first. To get the Pacifist ending, you must not kill a single creature, plus spare (and date) every main character you come across. The game has two "proper" endings - True Pacifist in which you save both the underworld and humanity, and Genocide in which you ruin everything for everyone - but it also features a wide range of "neutral" endings triggered by killing and Sparing specific characters.
