So, the turrets make the noise? Why? To create the atmosphere? To let the aliens know there are turrets? Because its cool? To hide the fact that theres no music? And why the turrets?
I guess it's fair, because the aliens have their own 'atmosheric' sounds, granted they can be considered less annoying but are ignorable. And sometimes I enjoy it, just relaxing in my base before another alien rush, me by my turret. Listening to the beeping, the swirling of the reactor, the occasional human changing his gear. Then the 1.2 turret sound kicks in like a punch to the balls, except its for my ears.
But we also have sounds like players spamming the taunt button, turrets making sounds when they're "spinning", Humans calling out "Come on!", beeping, screeching, roaring, shooting, jets flying, and the unexplainable fireworks.
Someone needs to create a song out of this.
