- "Combat 4" plays halfway through the Horde mode and perfectly hypes up the violence and carnage you're causing while fighting for survival.
- Aside from the frantic combat music, we have "Serenity", which sounds like it'd be right at home in another game such as Hotline Miami. A chilling, sinister track that seems to hint that there's something more running in the background that you don't know yet, but that you're about to figure out.
- "Complexity". The guitars gradually get heavier to make you feel you're a hurricane of bullets and death.
