1. Undertale Walkthrough Overview

Welcome to the walkthrough for Undertale, an indie RPG that you've likely heard about a while ago from its peak popularity back in 2015/2016. Because Sony requires most games to have trophies, the creator of Undertale has put in a list that's incredibly easy to complete. You don't even need to finish the game to get them all, but you should anyway. You bought the game, after all.
