Nooooot quite. The metal portion is being crafted by legendary Swedish SID metal band Machinae Supremacy (who did an excellent
a decade ago.) They are using this arrangement in the game and have confirmed that they have written new music as well. From watching the intro video on the Kickstarter page, it also sounds like there's new arrangements from Huelsbeck himself, so that is definitely exciting. From what I gather, this game has been in development for awhile and it's fairly close to completion; they just need a boost in getting over the final stages of development and distributing the game. Based on that, I'd presume Huelsbeck did the arrangements for this some time ago before the Turrican Anthology kicked off.It looks like a new experience from the DS Giana Sisters, and I for one couldn't be more excited.
