Legends of Localization Book 3: UNDERTALE follows the game’s Japanese localisation rather than its visual development. Clyde “Tomato” Mandelin wrote it with access to Toby Fox and the localisation team, according to Fangamer’s description.
The part that catches my attention is the working material. The publisher says the book reproduces spreadsheets and development notes alongside its explanation of translation choices. That puts the focus on how a line changes between languages, not just whether two final screenshots look different.
A different kind of behind-the-scenes book
The hardcover has 272 full-colour pages. Fangamer says readers do not need to know Japanese to follow it, and its Look Inside preview is a better starting point than assuming this is a language textbook.
I’d choose this over another general art collection if the writing is what stayed with you after Undertale. Check the preview first, particularly if you are sensitive to story spoilers. The optional Passport to UNDERTALE bundle is a separate book; make sure the selected package is the one you want. This pick is based on the publisher’s material, not a hands-on review.
