This is the ultimate guide to everything this map has to offer. Took me all afternoon and other peopels sources to get all this so credit to Pankake101 and Laggin24x who unbeknownst to them helped me create this guide.

Pack a Punch:
In order to open the room to pack a punch you must shoot the blue crystals around the map.
1. First one (In the video) is in the power room. Right when you walk in, take a right and you will see it on the shelf.
2. Second one is in the in the lab (left of the power room) in the basket in the back left of the room to the left of the window
3.The last one (in the video) go over the bridge and up the stairs. You will see it on the shelf to your right.
Once you have opened that room and gotten to the area surrounding the water. Simply link the pad in the center with the teleporter behind the 500 point door and you can teleport to pack a punch.

Teddy Bears (Music Easter Egg):
To start the music easter egg simply hold X (xbox controller) on each bear.
1. On the shelf to the left of the first door you will see it on the bottom shelf.
2. The second bear is in the lab on the shelf. When you walk in, it is on the right
3. The last bear in to the right of the "magical" door across from the soul box. Walk in and the bear is on the right.

"Magical" Door:
There is a skull on the floor directly in front of the "Magical" door up on the top of the steps. This is a soul box so youll need to feed zombies to it in order for it to open the door. I found that about 20 zombies does it but it changes from game to game.

High Round Strategy:
Honestly on this map their really isn't one but the best i could find is running around, juking zombies, in the mystery box spawn room. This is really tight and you really need a python or raygun for high mobility and the ability to quickly kill any zombies that block your path. I use a python and any lmg to farm up points until I've met the 25,000 point requirement to beat the map.

Conclusion:
This map is very close quarters and challenging. Soloing this map made me very frustrated but being as stubborn and dedicated I am I succesfully beat it. Now learning how the map works i could see the appeal of it and will definetely play it again but man is it tough!
