In the meantime i tried to extract all the files from the instalation file...it got easy to extract .pak file, then little complicated to uncompile the .pak itself (thanks, russian warspear forum ;) ), and i got to all the files, unfortunately not bitmaps, but ".map".
I tried opening those with many apropriate programs, but failed. Only one that worked was notepad, and it gave some interesting results- Maps in installation, are text files, later compiled by the game itself into graphics... damn :P
