That prelude is amazing, but I dont think it would have fitted with the mood of the game. Also I cant help hearing "Last Christmas" in my head at 2:53 of the prelude

As for the song used in the Dollet Mission I cant quite tell which I like better, they both would've fit the scene perfectly but I guess The Landing had the Liberi Fatali motif in it at 1:36 which ties it in with the rest of the game
