The Last Corridor

Undertale guide · The player faces Sans for the final judgment
← All areas in this guide

The Last Corridor is a grand, sunlit hallway in New Home where Sans evaluates your actions throughout the game. On Neutral and Pacifist paths, he explains the true meaning of EXP and LOVE and delivers your judgment based on your kill count. On the Genocide path, this area serves as the battleground for the climactic boss fight against Sans.

Secrets

Enemies

Sans

He only attacks on the Genocide route, deals Karma-based damage, and constantly dodges your strikes until exhausted.

Shops and people

  • Sans: Offers final judgment and commentary on your moral choices across your run.

Tips

  • In the Genocide fight, Sans ignores invulnerability frames, so high defense armor is useless; equip gear like the Cloudy Glasses or Torn Notebook instead to slow down the Karma drain.
  • For the Genocide route encounter, stock up on the best healing items beforehand, such as the Butterscotch Pie, Instant Noodles, and Face Steak, as you cannot buy them here.
