I am going to just guess, that if the game is pretty new, and the music sounds german and techno, that it is probably Rammstein. They seem to be getting into movie soundtracks fairly regularily, might be in the video game genre as well. If the tunes sound a little more dated than Rammstein, it could be Kraftwerk, they have been around for ever, German and techno, while Rammstein leans more toward metal as well.
Rammsteins most popular tunes seems to be Du Hast.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
