Easter Eggs - Map Pack 3

I have found 5 easter eggs. 4 are voice recording which explain the scientists training the zombies and the other one is the theme song.

where are they all? , i've found 2 of the radios

1. Animal testing lab in the furnace near the teleporter
2. Teleporter C on the shelf at the bottom of the stairs.

care telling us where they are, or are you that selfish?

The fourth one is in the beginning area. There's two barrels. Look down at the one on the left and hit X.

I see writing on the wall talking about Aether and the Trinity, anyone know more about these?

The six radios reveal ALOT of backstory about the zombies and hellhounds. They were apparently created when Dr Maxis and his accomplices were testing out the element 115 powered prototype teleporters. The subjects they used to test them were tele'd but shown no signs of mental activity when they reappear, becoming mindless (zombies). They also tested them out on Dr Maxis's daughters dog "fluffy". Apparently it went wrong. The dog seems to burst into flame and was teleported without reappearing at the mainframe. (this maybe is why the dogs appear out of thin air? Maybe the experiment cloned the dog and causes random wayward teleporting) Maxis's daughter spoted the experiment and started crying over the dogs fate, When the sound of "fluffy the Hellhound" is heard and Maxis and his daughter are seemed to be locked in a lab by another doctor, who laughs hysterically.

There isn't as much of a story as i thought just answers :\ It seems Richtofer started the zombies by locking somebody in the transporter and with a dog and they turned into zombies and somehow cloned.

IMO. Its all something to do with the teleporters. Maybe they opened up a rift to hell when they tried to send fluffy? I reckon the little girl that laughs is Maxis's daughter who seems to get killed by the first hellhound. Maybe the rift turns them evil or gets them possessed by a evil nature?

Also i reckon the Edward dude who locks Maxis and Samantha in the room with fluffy the hell-hound is Dr Richtofen.

Also another good one from Telexion Theory:

The mystery box once belonged to the daughter of Dr Maxis / Richtofen as a toy chest, (you can hear her in the radio transmission test 6), I believe this is why you can hear a woman crying on SNN and V. She lost someone close to her (daughter)... Her belongings and items now used by us as weapons (teddy bear, monkey bomb, ray gun?) In the most recent video by WTG u can hear her get ever more frustrated as you find more of her belongings and shoot them. "FINE GAME OVER!!!" doesnt this voice sound familiar? "BYE BYE!!" also... they made tests on her dog also in (test 6 radio) and this is why I believe she "controls" the dogs by saying "SEND ME THEIR SOULS" also in the same surreal voice. Enjoy x-x-x
