Not as good as some of the stuff I've read on here, but when the PS4 first launched I had my PS Camera plugged in whilst playing Warframe. I have a huge Cockatiel cage with 2 cockatiels in it and whenever they hear another bird, they think it's talking to them and go mental trying to communicates back.
So the game starts and one of the cockatiels tweets. The sound goes through the camera mic, out the other end and then plays back through the tv. The cockatiels now think there are half a dozen cockatiels trying to communicate with them so they talk back. The more they squawk (and they are fucking loud when they are excited), the more they hear themselves to the point it becomes deafening.
I hear all these random people in the game complaining about how their ears are ringing and I join in with them. The match was about 45 minutes and I'm pretty sure everyone left with a headache.
