*Reviving*
You get about 7% of the person you just revived points. Ex. 100,000 points, your revive them, you get 7,000 points!

It may vary on the perks they had, round, guns they had, how many zombies on the map, or just about anything.

Perks are things you find in an old style vending machine. If you have enough points you may walk up to the vending machine and hold 'X'. Doing so will make you get a bottle, take the cap off, and take a swig! If you want information on the perks click on one below for details.

Jugger-nog:
When you buy this perk for 2500 points your health get's boosted by +70%. Which gives you 3-4 hits until you go down. VERY helpful when you get to about round 15, you will need the perk by round 20.

Speed Cola:
When you buy this perk for 3000 points your reload speed becomes 50% of what it was before you bought the perk and rebuild's barriers twice as fast. This is helpful for Light Machine Guns and other guns that take a while to reload. Helps with Rap* trains and obviously getting out of tight situations.

Double Tap Root Beer:
When you buy this perk for 2000 Points your rate of fire is doubled! You can fire ANY weapon faster. This has NO damage affect, does not make you throw things faster, or anything but shooting. You may want to think twice about buying this perk. If you have something like an AK74u then you do NOT want to buy it, but for something with a low fire rate, go for it!

Stamin Up
When you buy this perk for 2000 Points your running speed and max distance goes up, a lot! If you have a Light Machine Gun then you are going to want this perk, if you have something like an AK74u then you may want to think twice. I would recommend it for all weapons, but it has a few factors. Think before you buy.

Quick Revive:
Solo:
When you buy this perk for 500 Points you will be invincible.. For one life. You will revive yourself. But there is a catch. You can only buy this THREE times the whole game on solo. But when you go down you get a Mustang and Sally until you get back up. Depending on when map you are on, the zombies will either run from you or run to you.

Online:
When you buy this perk for 1500 Points you will revive you team mates twice as fast. No one usually buys this because there selfish and only revive if it's in between rounds or being covered. I would suggest this perk simply because if you have all team mates alive its just easier. You get points from reviving so the perk can pay for itself. You get around 7% of there points when you revive them.

Dead Shot:
When you buy this perk for 1500 your accuracy and helps you snap to zombies heads when you aim down your sights.

PDH Flopper
When you buy this perk for 2000 you become immune to your own ray gun shots, or whenever you jump off a cliff. You won't die! Another thing, when you dive off stairs you will cause an explosion and inflict tons of pain to the zombies! Helpful depending on what map and rap* train you are running. If you have a ray gun, you NEED this perk!

Carpenter:
Rebuild's all barriers. Nothing else.

Death Machine:
Straight rip through zombies! Gives you a chain gun for 60 seconds. Slices through zombies and kill George in CotD in about 3-5 Death Machines to the face! It is only in Five, Ascension, and Call of the Dead. Might be back in Moon, I'll update when I know.

Double Points:
Half the effort and twice the benefit. All of your points are multiplied by two. Great when you need to upgrade, buy ammo, need to buy a perk, or just want points! Never hurts to have some extra points.

Fire Sale:
Need a gun, it only cost's 10 points, but hurry up! It's for a limited time only! For about 30 seconds you are allowed to buy a gun out of any random box for 10 points! Please take into consideration that it makes all boxes temporarily buy-able!

Insta-Kill:
Makes zombies back the hel* off! Kill every zombie - please know that this doesn't have any effect on George or the bosses on Shangri-La - in 1 hit, from any gun, on any level! Can either help or steal TONS of points from you. If your in Shangri-La on low level's you might just want to let the monkey's change it for you.

Max Ammo:
Screw buying ammo! This will replenish your ammunition, grenades, claymores, and spikemores. But be sure to reload before you pick it up, you will lose how ever many bullets you have shot in that clip. Ex. 89/150 in click, pick on max ammo.. You will still have 89/150 with max reserve.

Nuke:
Waepon on mass or minor destruction. This can vary between the best or the worst power up. This will kill all zombies on the map! But there is a catch, you only get 400 points. If you are on round 9 and the round just started, don't get it. You can get thousands of points compared to 400. But if you are on high rounds or about to get over ran, GRAB IT! Let the game do the hard work for you.

Pack-a-Punch Sale:
When you kill the scientist you get a power-up that looks like the pack-a-punch machine. Grab that and go into the transportation device and you will find yourself upgrading your guns But get ready, the zombies group up outside of the room and after a short while they will come in all at once.

The mystery box is by far your best or worst friend! You can end up with an extra pistol or one best guns in the game. The cost is only 950 points, but you might want to buy a gun off the wall first. The box moves on every map, except Nacht Der Untoten. With a fire sale, it cost's 10 points!

When you buy a weapon off the wall you are obviously given that weapon! But just incase you didn't know, you can keep buying that weapon and you will keep getting ammo for that specific weapon. You can buy any gun off the wall, but once you have 2 guns, you will have to get rid of one of the guns!

The pack a punch is one of the most crucial things in the game. What the PaP does is gives your weapon - not always all of them - increased damage, increased clip and spare, increased rate of fire, and red dot with a custom reticle. If you want to buy ammunition for it off of the wall then please keep in mind that it costs 4500 points! So get to the pack a punch you have to:
Kino: Activate the terminal in the starting room after turning on the power, then go to the transportation device and hold 'X'.
Five: Turn on the power, kill the scientist, take his power-up, go into the transportation device.
Ascension: Turn on the power, go to all three landers - go to Youtube if you don't know where they are - and use all three, go back to the power room and hold 'X' on the button next to the power switch, watch the rocket go off - if you have a ray gun, shoot the rocket and watch the BOOOOM - then go to where the rocket was and take a right and your there.
Call of the Dead: Turn on the power, watch for the lightning and then after about 10 seconds you will see the light is only pointing one place, GO THERE.
Shangri-La: There are 4 platforms on the floor, find the - lets say you have 3 people - 3 platforms that are sticking out of the ground - go to Youtube if you don't know where the platforms are - and stand on them at the same time, when you do so you should see that the spinning doll has stopped spinning. Go back to the starting place and you will notice a HUGE staircase. Go up that and upgrade.

If you play COD Black Ops then you know about Nazi Zombies people who play COD WaW know about Nazi zombies too! Little do most black ops players know there is a story i believe this goes for WAW as well. Anyhow I get a crack out of every time people I play with get game over on black ops in zombies these days because most people may not know but the "master mind" controlling these zombies is a little girl named Samantha Maxis. She is the daughter of Dr. Maxis who died. Samantha was killed by her dog Fluffy after he had because a hell hound, the first one with that. Edward Ritchford, her father quote on quote "Loyal" assistant was there when it all happened him and Dr Maxis were there doing something on Der Riese (Thats where it was) Samantha just so happened to be there and Fluffy was already a hellhound Samantha asked her dad "Daddy, what are you doing to fluffy?" she was crying her dad replied "DAMNIT SAMANTHA! I told you never to come in here, EVER! Get her out of here Ritchford" Ritchford, but lets call him Lord As*hole did what he said and Samantha screamed. Samantha went to her father scared and crying the Lord As*hole had left them went through a teleportation device and left them. "Daddy what's happening to fluffy?" Samantha sobbed "There there Samantha. That's not fluffy anymore." he said "Daddy, I'm scared" Samantha said. This is when she was killed and Dr Maxis supposedly left her and killed him self. Either he did or didn't leave her it is still a fact he had hung himself on Der Riese, the hanging man where you can only see the legs easter egg is him. People also think he was killed by fluffy too. Anyhow Samantha is the giggling girl in the mystery box too. When you throw a gersh with a certain character in Ascension he says "Say hi to Samantha for me!". Sometimes when you kill a Zombie it says 'Samantha!". Also you can go to Samantha's room through the teleporter in Kino Der Toten (The dirty and clean versions of her room.". And the teddy bears are hers I believe.

Also don't believe this is true the story with Dr Maxis and Edward. Well listen sometimes you can hear Ritchford say when Hellhounds come "Fluffy is that you?" but it doesn't sound like fluffy due to his accent and in Der Riese everything involving the teleporter he left the Maxi's in or the room where it happened he'd know what door leads to where and all of that. Also news papers believe Dr Maxis who died was only missing know one knew he was dead but Edward mad it clear he did. Most of the hidden songs have something to do with Sammy. And in the loading for Kino Der Toten you may hear a recording of Edward and at the end he says "I wonder where that little girl is?" he ment Samantha!!!!!
