Players have already translated the runic language in Tunic.
Throughout the game, instructions from characters, signposts, and the in-game manual are written in a made-up runic language. Players aren’t required to translate it; instead it adds an air of mystery to the foxy adventure and forces players to analyse visual clues instead.
However, some eager players have begun diligently translating the runes, including Reddit user oposdeo.
Oposdeo, who works as a programmer not a linguist, has only beaten a couple of bosses in the game so far, but has managed to ascertain vowels, consonants, and grammar structure of the fictional language. Now to translate all the manual pages.
