Fatherland, the main theme. In contrast to the original Sniper Elite's main menu theme, this one is much louder and more bombastic, which helps to indicate this game's status as a Continuity Reboot.
The Waiting, one of the themes that plays during certain levels set in Berlin. The first 3/4th plays when Fairburne is perfectly concealed, reflected in the quiet style. Then, when the final portion begins playing, it suddenly shifts tone to reflect the shift to combat, which in this game is frantic and quick when it does break out.
Track 3, the combat theme of the Halfaya Pass mission that plays when engaging the Panzer III at the end of the level. An intense theme perfect at showing how (initially) one-sided fighting against a tank with only a Sniper Rifle and a handful of of mines is.
Track 4, the Tiger I tank theme, reflects perfectly on why exactly the Tiger I is considered as The Dreaded, what with the tense and heavy notes used throughout.
Combat Theme 1 plays when Karl's cover is blown in the first and last levels of the main campaign. It captures the feeling of being outnumbered and outgunned in the Italian countryside, surrounded by Nazi and Italian fascist troops.
