One of the most acclaimed video games of the past decade, solo developer Toby Fox's indie hit Undertale has enchanted a fanbase of nearly 4 million players worldwide through its heartwarming story, quirky characters, and Fox's own trailblazing musical score. Undertale introduces players to a secret world of monsters who were sealed underground long ago with an ingenious twist in perspective: players can resolve each encounter nonviolently, inviting us to empathize with those most different from ourselves.
