Hi when you go into the bunker to switch the power on in spiking the guns if you walk back up the stairs just before the spiral stair theres a computer in the room that says pick up…so i pressed square and nothing happend as nothing is there after doing this the reloading sound of the guns dissappear after this.I only noticed this because this caused me to close and reopenin the game wich stopped the doors from opening too.The only way to get the sound back is close the game down.
