Does anyone know what scale the first acoustic part of Call of Ktulu by Metallica is written in?

Also if you know any other bands or albums that are similar to that album that you could recommend me that would be appreciated.
It's a near direct copy of Hangar 18 by Megadeth. Dave Mustaine wrote the chord pregression. But yeah D minor.

Similar to Ride The Lightning? I really can't think of many even in Metallica's catalogue. Maybe The New Order by Testament or Master of Puppets by Metallica. It's a shame though I really love that album, probably my favourite of all time.
