As I first walked around on Waterloo coming from the attackers side and going the stairs with the MG up I thought there was a rattle snake hiding somewhere. Later I found out the sound was coming from the rat family.
The sound doesn’t fit at all and is by far too loud! It’s a sound the player cares last about, so please turn the loudness down or add them to ‘ambient sounds’ which you can completely turn off.
Pigeons are also too loud.
