UNDERTALE / ROUTES & ENDINGS
Three route families. Many consequences between them.
Neutral, True Pacifist, and Genocide are useful names for Undertale’s broad route structure. They are not three equal menu choices: each follows different conditions, remembers different actions, and leaves different consequences.

This guide explains route conditions, late-game areas, the Barrier, and persistent consequences across later playthroughs. It is a route map, not a spoiler-free recommendation or step-by-step walkthrough.
The three commonly discussed Undertale routes
| Route family | Broad condition | What makes it distinct |
|---|---|---|
| Neutral | A completed run that does not satisfy all True Pacifist or Genocide conditions. | Many ending variants respond to who was killed, spared, or befriended. |
| True Pacifist | No EXP or LV gain, required friendships, and the later story sequence unlocked after an eligible Neutral completion. | Opens the True Lab, resolves the Barrier, and provides the complete credits sequence. |
| Genocide | Deliberately exhausting the required kill count in every area and defeating the route’s required bosses. | Changes encounters, music, dialogue, bosses, and some later endings even after the world is restored. |
Neutral is a family of outcomes, not one ending
Neutral covers the space between the strict conditions of True Pacifist and Genocide. Its ending phone call and the state of the Underground can change according to character deaths, friendships, LV, and which major encounters were spared.
That makes Neutral the broad default category rather than a single morally uniform route. Two Neutral playthroughs can leave very different consequences.
Why True Pacifist normally follows Neutral
A first run can preserve the no-kill conditions needed for Pacifist, but the complete True Pacifist ending path normally opens only after an eligible Neutral ending has been reached. The player can then continue the same SAVE and complete the remaining friendships and story sequence.
Calling a no-kill first completion “wrong” misses the point: the game deliberately makes later knowledge and return part of the structure.
A violent run is not automatically Genocide
Killing many enemies or choosing little mercy can still lead to a Neutral ending. Genocide requires systematic area-by-area exhaustion and specific boss outcomes. Fans sometimes use “No Mercy” more loosely, but it should not replace the stricter route definition.
The distinction matters when reading guides, discussing endings, or interpreting how the game reacts to player intent.
Routes are consequences, not personality diagnoses
A chosen route may reflect curiosity, completionism, role-play, challenge seeking, or a desire to see alternate writing. SoulVirtues.com does not infer someone’s Kindness, Justice, or other real-world score from the route they played.
For the game’s color mechanics rather than its ending structure, read the SOUL mode guide.
