Moscow Rhapsody was the game Illusion Softworks(original H&D2 developers and Vietcong/Pterodon) had planned to release in 2009. They were working on it after H&D2 SS was released in 2004. It got cancelled after the company was taken over by 2K and developers had to let go of their beloved projects.
This is the demo... it never got to be a full game. Who knows, if might have been a good chance to have a H&D3 in the series
