8 Video Game Endings That Cost You EVERYTHING
2. Undertale
The brilliantly bonkers Undertale has three main endings, depending largely on how players deal with the enemies they encounter throughout the game.
The Pacifist ending is achieved by, shockingly enough, refusing to kill any of the game's enemies, while the Neutral ending is unlocked by killing some, but not all of them.
And then there's the Genocide ending, which also true to its name, can only unlocked by killing every single enemy in the game. This requires players to not only kill every enemy they fight, but also hang around and trigger random encounters until all areas have been fully wiped out.
This will lead to an ending in which players battle Sans, arguably the best and most challenging boss in the entire game, before Chara shows up and straight-up erases the entire world.
And better yet, in order to replay the game, you'll need to then give your soul to Chara, in turn restoring the world.
