Great to hear you like us enough to go to all that trouble, but unfortunately we're not able to use player-made translations in the game. We need to be able to verify and modify all texts, both now and in the future when Barotrauma is developed further, so player-made texts would still need to go through the formal process. As such, our publisher always handles the entire localization process. What you can do, however, is publish your translation as a mod, and please give feedback if you spot mistakes in the localized texts!
