Thoughts on the scenario after completing "Hammers of Fate".

yes, there’s only one mission there; you can download it at

it’s 64 MB
(but in the Gold Edition, the subtitles are in Russian, while in this one, they are in English (the voice acting is in English in both))

maybe there’s one with Russian subtitles on Nival.
