Fallen, you don't have to do this. First, translating maps as "300" need about 3-4 months of daily work. Second, from english to russian is very hard and you will have to check ERM script and get story conclusion and plot by analyzing the codes.

I know how it works, as I am translating right now the biggest chinese mod/map, "The Dragon Slaughter". We are two to work on it (me and Jim Vogan) and spent 3 months to polish things and it is 70% done only (177 pages of only text and instructions). And we payed also a professional translator who screwed most of Heroes specific terms, so he did not help.

I wish Heroes had some universal language, but unfortunately not. And there is still Phoenix mod to translate, my year is full of projects.
