This reminds me off COD WW2 zombies. Where they do things similar where the music gets more intense with the more enemies surround you. Makes sense as Glenn also worked on Dead Space.
@A.K I will agree some weapons don't sound great but I honestly do love the game. Better then Vanguard. There are some things I like about it but it's just not it.
Imagine that. You are 9 years old. You've reached chapter 4. You have an understanding of how lonely you are in this place. And then this monster appears to this accompaniment. Your hands are shaking from the sheer size of this monster. Bullets are wasted. That's all. The point of no return. You've run out of ammo and there's nowhere else to run. You pause the game and exit it.
