It took my a couple years, but I've released the full OST on SoundCloud! The first movie was made up completely of free stock music, so that's why there isn't a release of that one. Anyway, this is actually a slight revision from the movie version, with some minor changes and edits through most of the tracks (though not all).  Save maybe the title theme, it's not particularly different--basically, if you liked the original you'll probably like this more; if you disliked it you might dislike this less; and if you didn't have much of an opinion on it... well, you probably won't after this either.  https://soundcloud.com/mxyl-valtapaz/sets/abydos-incursion-ost
