While playing solo, knife the entire 1st round and open the top door that leads to a possible mystery box. If it is there, throw a grenade under it and walk away. Wait for it to blow, then go to it but have your back facing the box. Buy it and stay looking away! When it says trade weapons,buy with your back facing it! By doing this, you get a Python, Thundergun, Commando, and AUG.
The following perks are available: Speed Cola, Juggar-naught, Double Tap, Stamin-Up, Dr. Phlopper, Quick Revive, and Deadshot. The Deadshot perk allows you to snap-aim (holding down your ADS while an enemy is near) to the zombie's head instead of its torso.
Access the Central Intelligence Agency Data System and enter "rlogin dreamland" as a command. You will be prompted to login with an account with MJ12 access. Use the following usernames and passwords to continue.
To reach the Pack-A-Punch on the Zombies mode "Five" map, make a crawler and go into the middle room and adjust the DEFCON level to DEFCON 5. Every teleporter will take you to Presidential Suite. All switches are in that room; 3 are upstairs and 1 is downstairs.
In the level "Numbers," after interrogating Clarke, several enemy soldiers will appear at the end of the long hallway. Shoot all six Nova 6 canisters and you will be able to collect a cassette tape in the office behind where you started. Throw a flashbang to blind the enemies so you have less interference when taking out the canisters. After picking up the tape, continue until you reach the part where Weaver and Clarke both jump off the roof onto a mattress. After they jump down, Clarke will ask Weaver to help him move a fridge out of the way to his first weapon stash. Once they do, go inside and look to the left. There should be a place to put the cassette. Note: When picking up and placing the cassette tape, the game will not prompt you; you must have seen it being moved yourself. After that, the screen will shake and the Thunder Gun will appear out of the wall. It has twelve bullets, and it is reloaded at checkpoints.
The new Zombie map, Shangri-La from Annihilation DLC, features immortal zombie monkeys. At first they don't appear to do anything, though they respawn when they are killed. However, once a power-up drops nearby, these zombie monkeys will snatch up the power-up and attempt to take it back to the shrine. While running back to the shrine, the power-up in the monkey's possession will switch between the different power-ups. If you kill it, it will drop whatever power-up it held last, but other zombie monkeys will attempt to retrieve it as well. If you manage to grab it before a monkey does, the monkey tries to loot 50 points from you.
In the Zombie map "Kino Der Toten", there is a teleporter in front of the curtain on stage. When you use this teleporter, you get sent to the room that has the Pack-a-Punch machine and a window. If you wait about a minute you'll be teleported again to one of several secret rooms. Inside the secret room that contains the presidential seal and a projector, there is a desk. On the desk there is an old roll of film which you can pick up (be warned you will not be prompted to pick it up, you just can).
The easiest way to fight George is by not fighting him. Shooting him, blowing him up, and even knifing him will cause him to roar in fury, then charging at full sprint toward you and your allies until everyone is dead. If this occurs, you can lead him to any large body of water to calm him down. Until you acquire the new wonder weapon and upgrade it via pack-a-punch, you will not be able to kill him. Also, the power must be active before you can damage him.

To play "115" by Elena Siegman, do the following. Find the three meteors. The first meteor is located on a pedestal in a corner behind the soda in the main lobby. The second meteor is located on a pedestal in the dressing room near some mannequins. The third meteor is located in the room upstairs near the alleyway, on a "dresser" with black marquee letters. Note: The meteors appear as red veined rocks. Hold [Use] on each meteor until your character says something or the veins in the rock glow red. After all three are found, the song "115" by Elena Siegman will play.
The power must be on to do this glitch. Go up to the teleporter, and go to the left of it near the barrel type things. Simply walk in the corner, scooting back by the curtain, and then justturn around and shoot. Only 1 dog can be in the glitch at a time, otherwise they will start hitting you. Note: this will not work if you have updated the game.
After buying the box for 950 points, pull out your m1911 pistol that you start with. Shoot two times in the left and two in the right, then lie down, stand up and do the same. When you automatically empty your clip you should have the Ray Gun.
1. Grab a friend to help you. 2. Get a class with a tactical. 3. Find a corner. 4. Put your tactical in the corner. 5. Keep putting care packages in the corner (don't let the crate fall on the tactical). 6. After putting the care packages in the corner tell your friend to kill you. 7. You will spawn in the care packages. 8. Now your friend stands in front of you (not too close). 9. Start knifing your friend, but you won't kill him. 10. After knifing him for a while you will get out of the map (some maps kill you if you walk on a roof or something).
The power switch can be found on the half-sunken ship to your right when you begin. The boat that covers the entrance is 500 points. When you go up the ship's side, proceed straight until you see a stairway to your left leading upstairs, which is worth 750 points to enter. Once inside, go to either the right or left of the cabin and go inside, where you will find a stairway leading up again. Go up and move around the room to find a door worth 750 points. Open this to find the power switch to your right when you walk in.
Go in front of any house in Nuketown and go to your right. Before getting in the backyard, stop at the corner of the house and face what looks like a flower box. It should say Press A to get on top. Afterward, climb up the wooden lattice that looks kinda like a ladder and you should be in front of one of the windows on the top floor. If the window is already broken, you can climb inside.
Find the three hidden teddy bears holding a sickle and press [Action] next to them to play the song "Abracadvre" by Elena Siegman. The first bear is located left of the Olympia shotgun in the starting room. The second bear is behind the fence across from where you purchase Claymores. The third bear is by the lunar lander near the Speed Cola machine.
At the Battle of Khe Sanh, you will be informed to clear the trenches. There is also a nearly inaudible clue telling you that there are barrels full of napalm but it does not tell you what to do with the barrels. You have to run to two of the large striped barrels near the bottom of the hill and kick them down into the trench. Then, hide behind the sandbags and shoot the VC until it's clear. Make a run for the nearby barrel and use the prompt to stab it and kick it down the hill.
Before using either the platforms or zipline, you must first activate the power. After that, you must unlock the area that the platform or zipline ends at, otherwise it will not take you anywhere. The zipline can be used if there is no notice saying "Closed set" (indicating that you must unlock it) or "Power must be on" (power needs to be turned on). Once the zipline is active, jump into it near the edge. The springing platform can be used once the area (lighthouse base) is open and the power is activated. When you stand on it, you will hear a compression sound. Then, after a moment, it will launch you away. Beware as zombies and George can also use them.
On the Zombies map Five, go up to the red telephones and hit the button prompted to change the background music to "Don't Back Down" by Eminem. There are three red telephones total: One by the Quick Revive machine, one on the second floor in the center of the room, and a third one in the room with the Pack-A-Punch machine.
Shoot the mannequin heads in Nuketown you'll hear "Sympathy for the Devil" by the Rolling Stones.
On the Zombie map "Kino Der Toten" there are three pieces of a meteorite located throughout the map. The first is near the stairs when you start the level, the second is in the "boiler room", and the third is in the "dressing room." Hit the prompt when next to the piece and your character will say a line about the meteor. When all three pieces are found, "115" by Elena Siegman will play.
Before attempting to unlock quite possibly the most elaborate easter egg ever, make sure you satisfy the following:
Have 4 players. Everyone involved must have the trophies "Ensemble Cast" and "Time Travel Will Tell" from the previous Zombie maps, Call of the Dead and Shangri-La, respectively. Three Mystery Box weapons Wave Gun, Quantum Entanglement Device (QED), and Gersch Device. Excavator “Pi” to reach tunnel 6.
First, activate the power. Once you do, locate the four computer terminals that sit in the outside starting area. Each computer terminal lights up a specific color, and you essentially must play “Simon Says.” When you successfully input a round of sequences, all four terminals light up green, signaling the next step.
Head into the lab area with all the servers and use a hacker to hack one of four red buttons along the wall. Afterwards, some terminals light up green in the adjacent room. Have one of you hack all four of these green-lit terminals, and at least one other person press the four red buttons within seconds of one another until they all remain lit.
The third step involves the Excavator breaching tunnel 6 (where the M16 is). It’s easier if you only open up the doors through tunnel 6 when you begin. Afterwards, get rid of the Excavator by hacking the proper terminal in the Receiving Area.
If everything has gone according to plan so far, you’ll notice a round stone floating near the M16. Knife it to make it float around. Keep knifing it to move it along. Note that if it seems to have “hid” itself, simply shoot it in the general area where it disappeared to make it re-appear. This floating stone eventually bumbles its way to the disc at the base of that strange pyramid.
A cylindrical tube emerges from the right side of the pyramid’s base. Apparently, zombies’ souls belong in this tube. For the tube to collect these souls, you’ll need to kill several zombies near it, and you’ll watch the tube slowly fill up. When the tube is completely filled with zombie souls, you’ll next need to flip the switch on the wall to the right of the tube. Congratulations on unlocking Cryogenic Slumber Party! From here, you need Richtofen’s Vrill Generator to proceed. This is gotten by completing the previous Easter egg trophies. Whoever is Richtofen will have the Vrill Generator at the bottom of his screen.
All players will have the Death Machine power-up for about 90 seconds, so head back to Area 51 (where you first started) to earn some major points on zombies, if any. Look to your right and toss grenades at the plates on the shelf. A friend with the Gersch Device needs to then throw a Gersch Device to where the plates have fallen to suck them up and move them to the teleporter. Quickly get on the teleporter to be transported back to the station.
You’ll now find the plates lying on the floor in front of the Quick Revive. Use the QED to shuttle them to the computer in the corner of the same room. Whoever is Richtofen must place the Vrill Generator in-between the plates to activate a cut-scene. Have Richtofen repeatedly press SQUARE at the computer keyboard until the voice-over ends and the color of the computer screen turns and stays green.
Take the glowing Vrill Generator and return to the pyramid. The Vrill Generator will insert itself in the engraving and cause more cylindrical tubes to rise from the corners. You’ll need to kill enough zombies to fill up every tube. Once all four tubes have been infused with souls, activate the switch again to drain them.
Richtofen must grab the revealed Vrill Generator to earn him perks that stick around permanently. Use the QED to transport the floating stone back outside. It ends up right by the “Simon Says” computer terminals. Suck up the floating stone with the Gersch Device.
The stone goes to some out-of-reach rockets, which launch toward Earth, after completing “Simon Says.” Once the rockets smash into the Earth, you earn "Big Bang Theory."
Go downstairs, then stand in front of the large elevator. Go left along the desks next to the teleporter until you see a railing. Stand behind so that you can see it long ways. Dolphin dive on top of it. When on top of the railing, stand up and keep jumping up until you are on the teleporter. Zombies cannot harm you unless you get too close to the stairs. You will gain lots of points because the zombies will gather up, and it is easy to shoot them while they are crowded together.
Note: The Call of the Dead map pack update is required. You also must activate three meteorites. The first meteorite can be found right in the starting area by the canister. For the second one, you must reach 750 points. Open the path to the right (while facing the lake) of the starting area and head upstairs, then pass the blockade and enter the room with the tables. On the far side is a meteorite lying on the seat. You'll need 750 points to open the path to the lighthouse. Underneath the large staircase, leading up to the lighthouse, is a room. Facing the staircase, turn right and make your way to the room below. The meteorite is here. After finding it, "I'm Not Ready to Die" by Avenged Sevenfold will play.
Locate the three red rotary phones throughout the Pentagon that ring and flash. The first phone is located at the start, after opening a set of doors in the corner. The second phone is on the catwalk circling the room after leaving the first elevator. The third phone is in one of the rooms after leaving the second elevator on the floor that the power is on. You can find the phones by following their ringing. Look at the phone, then hold [Action] until you hear a busy signal. After the third phone is accessed, the song "Don't Back Down" by Eminem will play.
The "Frag Master" trophy can be unlocked by performing any of the following three tasks:
During the battle of Khe Sanh when the NVA are pouring out of the tunnels in the background, throw grenades into the crowd. You are bound to kill some of them.
Get five of your friends to join the other side. Tell them to cram together, then toss a frag grenade.
This requires two players. Blow the legs off five zombies and have the other player to stand in one place while the zombies crawl towards them. When they are all attacking your friend, throw a frag grenade.
Unlock the following Custom Class slots by reaching the corresponding Prestige levels. Note: After unlocking a slot, the pre-set class for that slot will not be available until you reach Prestige again.
At the title screen, use the Right Analog-stick to look down at your hand when you are locked up. Repeatedly press LB + RB to escape the from chair. Move around the lab and find a computer. Type in the command "DOA" to start a zombie killing mini-game. Use Left Analog-stick to move and Right Analog-stick to shoot. Note: You can also enter the command "HELP" at the computer to get a list of other commands.
On "The Defector" mission, when you go inside the building with Bowman, Reznov, and Woods, (the one where the man is crying over his dead friend), go upstairs to find two VC in front of you and three more behind the window next to them. Aim precisely so that you can kill all three of them in one shot. This is a checkpoint; if you miss, kill yourself and try again.
Wait until a zombie drops the "Death Machine" perk while making sure you're near George when you pick it up. Shoot at him as much as possible. Since the Death Machine has unlimited ammo for a short time, this will deal significant damage to Romero. Even if you pull him into the water and he returns to normal, this will still inflict damage. It will require a massive amount of damage to defeat him. You do not necessarily need to turn the power on or kill him near the water; just as long as you keep doing damage to him, any weapon will bring him down. You will notice that his light hammer turns from blue to orange when you are close to defeating him.
