Well, it's just the '-us' ending being omitted. Icarus > Ikar, Daedalus > Dedal, Horus > Gor, Odysseus > Odyssey, etc. :)

I was not necessary thinking video game... Perhaps a novel?

Well, the three books (four, but a fourth one is much inferior IMHO) aren't translated to other languages as far as i know. I guess the estimated sales are not enough for publishers to undertake such project (most characters in the books are Russian).

I see! quite a pity there again! Was the forth book corresponding to the factor K storyline?

Yes, it is.
