Well, last I checked it was available for $5.99.

Although, I'll be honest Takeshi, you might be better either waiting for the Deluxe version or downloading the Abe-A-GoGo soundtrack, because those have both cutscene and game music in them (albeit with tracks missing from the latter).
Ah, Slog Chase... :)

It will be interesting to see how complete the "deluxe" version is in comparison to the Abe-A-GoGo soundtrack. Guess we'll just have to wait and see, and from there I'll know if I need to remake my full mixes or not.
