First impressions:
I'm liking it so far. It does sound a bit more electronic here and there, and there is something about the production that's pop/dance style, but not really the music itself. A hint of glossy 80s rock, perhaps? There's not a lot that's instantly catchy, that's what marks it out as different to previous albums.
Loved the first two tracks for the drama, and I definitely wasn't expecting Rorke's Drift to be a fast one. There's nothing terrible on the album (I could never get by with Ballad of Bull), it's generally solid Sabaton fare. Bannockburn is better in context of the full album, although I can't get away with that cheeriness, even if it's fitting with the Scottish pipe music effect.
Winged Hussars is in a similar vein to Carolus Rex, which isn't a bad thing at all since that's my favourite Sabaton album, with a touch of Art of War in the chorus. Probably my favourite track after first listen. The Last Battle is the most catchy track to me. Camouflage is a classic Sabatonised cover, although I'd fully expected something slower and closer to the rhythm of the original, which is surprisingly Sabatonny in its own right. It's got whoa-ohs in it, so a possible live song. Not sure about the Priest cover. Not bad but not sufficiently different, really.
