Life on the server
Two languages, one chat
Pick your language once and everything switches to it, from the menus to the chat. Everyone writes and reads in their own language.
In the game/language
HeliosMine is played in English and Turkish. You are asked for your language when you first join, and /language changes it whenever you like.
Everything in your language
Menus, quests, item names, announcements, what the townspeople say and the in-game wiki all come in the language you picked.
Chat translation
Everyone writes and reads in their own language: a message written in another language reaches you in yours. Turkish and English players talk in the same chat with no trouble. You can turn translation off in the /language menu.
