I know this because the Nike-it, the Administrator of the forum, write about this in this forum and also because in the demo are folders for various languages.
There are several translations in English for the game , many simply are the texts of the demo , which is the translation of the whole game to English.
There is also a translation into my language - spanish - made by a fan, with high quality . Finally, is possible for me understand the history of Danko
. The history of the game is very good . And is better with the voices in russian and subtitles in our lenguages
