Australia Day ft. "Five"

Alright, so today, i did something that i hadn't done for a while...
I got sunburnt.
It was Australia Day, but, never the less, i still managed to get some COD in.
Unfortunately, today my Xbox Live decided to expire on me :\
So, i played Zombies with a couple of friends on split screen.
And i have a couple tips and tricks for the map "Five".
So, when you start in the main room, you'll notice their are 5 entrances for the Zombies to get in; 4 windows and one wall.
A good way to rack up points in this Map is to break all the windows, and repair them, to get a couple extra hundred points.
Also, stick to just knifing and the pistol for the first couple levels.
In 2 player, my friend and i managed to get up to level 5 without grabbing any weapons, so with 4 on Xbox Live, you should be able to last till you open the door.
Now, i recommend not advancing to the next room ( which costs 750 credits) until you have enough credits to purchase the Machine Gun (1000 credits) on the other side of wall, because with the 4 extra Zombie entrances, you'll need it.
Now, if you plan on advancing, make sure you and all your friends have plenty of credits.
So clear the debris (1000 credits) and get in the elevator.
From here, you can chose to advance, or simply camp in the elevator.
If you do activate the elevator (250) then be prepared, and reload on your way down.
When you get down, you'll find a control room.
This room has many entrances, (i think about 5) and a currently unactivated teleporter in the middle.
Now, there is more debris to clear (1000) and then another elevator to take (not sure how many credits, will update how much later).
If you take this elevator, you'll find what looks like a laboratory. You'll be happy to learn that the Power Switch is down here, making all the Perk machines and Traps available.
Be aware however; there is some strange Zombie that steals your hard earned weapon!
It wore a lab coat when i found it, but it may just take the form of a generic zombie.
Now, when you activate the Teleporters, the Gas Zombies appear.
These buggers are annoying, but i'll do a post/info column thing about them.
Anyway, possibly the most annoying thing to happen is to be left alone downstairs by your teammates while waiting for the Teleporter to re-charge.
The Teleporter takes you straight into the Control room, so it can be handy for quick escapes.
So, hopefully this Walkthrough/Tips post can help you get to that much coveted level in "Five".
Anyway, Comment, link me to a video, or suggest a future post for me.
Kcigam out.
