Call of Duty: Modern Warfare 2 (Xbox 360)

"Armor Piercing": Juggernaut

On the Special Ops level, "Armor Piercing", take the Barret .50 and kill the first Juggernaut. Then, continue to the scaffolding on the outside deck of the oil rig. Plant claymores along the path the Juggernauts take (which would be from the gate and along the inside wall, on the pillar opposite from the scaffold, and up the scaffold ladder). Plant about three of them and wait. When he arrives, wait for him to get to the top of the ladder and shoot him in the head with the Barret. If it does not kill him, plant another claymore the next time. If it does, you will see the Juggernaut's body fly off in the direction you shot him, but he will not fly off. Instead, he will get stuck in a random object.

"Breach And Clear": Easy Veteran completion

Try to have two players for this trick. Before breaching the wall, grab a Striker and an AA-12. Once you breach, run to one of the sides with the AA-12. Keep running and do not stop killing enemies with one shot. Once you get to the part with the Riot shields, switch to the Striker. Run towards the shielders while firing. Almost every time when you use two players, one person will get to the hole and the other will either get to the exit or go to bleed out. If you bleed out, crawl past the enemies. You cannot die and have about two minutes to drop to the bottom.

"Endgame": Nazi trucks

Select Campaign mode and play "Endgame" in Act 3. After exiting the caves during the speedboat chase, notice the village on the hills to the left coast. You can find a Nazi truck from Call Of Duty 2 behind a low wall near a pontoon and another one farther down at a jetty. Note: You will lose Shepherd by stopping to find the trucks.

"Endgame": Shepherd comments

When at the end of the last mission, when you are supposed to kill Shepherd with the knife, after the helicopter crashes stand next to him but do not kill him. After some time, he will begin to say things such as "You know killing me won't change anything" or "You're a good warrior", trying to persuade you not to kill him.

During the final mission where you must follow Shepherd and attempt to stab him while dazed, do not go near him while he lays against the car. He will say one sentence at a time, slowly, and his final sentence will be "But you were never willing to do what must be done" or something similar. Note: If you get too close to Shepherd, he will smack you against the car. If you go too far, he will cut the speech short.

"Estate Takedown" Spec Ops mission: Easy completion

Note: This trick is much easier with two players. As soon as you start, you will be greeted by a Juggernaut. Shoot him in the head with the sniper rifle a few times. Note: There may be other enemies, and the Juggernaut may not appear until you enter the safe house. Once you clear the bottom floor, go to the armory in the basement. If you have two players, have the person that is better at sniping collect the WA2000. Stock up on ammunition. The ammo containers are difficult to find; you must search carefully for them on the right side. After you collect your guns, clear the main floor and the top floor. Once you clear the house, have the player with the sniper rifle walk upstairs and go to the room to the left. Once they enter that room, go to the windows by the table with the sentry gun on it. Snipe out of that window (it is located in the front of the room). Have the other player guard the door while standing at the top of the stairs. Multiple Juggernauts will come through the front doors. Plant a claymore at the bottom of the stairs to slow them down. If you partner sees one, he or she must alert you so that you can use the sniper rifle on him. Keep repeating this until you complete the mission. If you need more claymores or ammunition, the armory is in the basement.

"Estate": Enter the ceiling

In multi-player mode, get on the railings on the top of the stairs. Back up as much as you can, then sprint then jump in the northwest corner and you will be in the ceiling.

"Estate": Infinity Ward Gamestation

Select Multi-player mode and the "Estate" map. Search the home theater to find an Infinity Ward Gamestation 5 game console.

"Evasion" Spec. Ops mission: "3 Star" rank

At the very start of the mission, run forward until you see the crosses or about four or five seconds in. Go to the right side against the fence and get prone. You must do this fast so the guards do not see that you are advancing toward your beginning position. Remain prone until four guards pass by. You can crawl to a better position to view the advancing guards if desired. You can get up and continue to the right after the fourth guard passes, but stay along the fence. Then, run and go under a pipeline. If you stop and look to the left where the pipeline goes, you will see a few guards; just ignore them. Move slowly and continue to the right. You will soon encounter a guard and a dog that will come up the path to the left. If you run, then you will not see the guard. There will be another path to the left with two guards on the far side of it. Ignore this path and continue a few more steps to get beside a tree in the middle of your current path. From this tree position, you will be able to snipe those two guards. Before rushing onward, make sure to take out the guard and his dog in a small clearing to the left. You must advance slightly along the fence for a clear shot. Once that is taken care of, you can now continue past the two guards you just sniped. Get prone a few steps ahead of them. There will be a small clearing. A patrol consisting of three guards and two dogs will pass by. Slowly follow after the last guard, but make sure you keep your distance or risk them seeing you. After a short distance down the path, there will be one guard and a dog stopped just past the pipeline, but on the path. Wait for them to leave before moving ahead. After a few more steps, get prone and wait for another guard and his dog to leave as well, but stay close to the pipeline. There will be a guard walking to your left as well going toward where you came from. Once those guards leave the area, crouch down and sneak up the bank of snow and go underneath the large pipeline. Once you move ahead enough following the pipeline, you should see two guards at the top of the hill in front of you, just after the pipeline turns to your right. Quickly snipe them and move up the hill to their position. Once on top of this hill you will see your green smoke and can quickly slide down the other side to complete the mission.

"High Rise": Scaffold

Spawn to the middle of the map. Go to the edges. Look for scaffolding that has one side lower than the other. Go down into it, then look at the building. There should be a little part standing out. If you see it, jump onto it. Start walking. Do not try to get to a lower scaffold or you will die.

"High Rise": Sniper position

Look from the center of the map at the cranes, then to the left side of the map. Go that side's back left corner. You will see broken scaffolding. Sprint from before the ledge and jump to the left outside yellow railing. Note: The railing is vertical. This is a hidden ladder. Climb up this railing/ladder to the top of the scaffolding. Walk to the right of the scaffolding along the ledge of the building. You will eventually reach another scaffolding. Climb onto this scaffolding. Walk to the top. Look towards the building and climb onto the higher ledge. Follow that ledge going left. Keep going forward and you will reach the roof. This is a great sniper position. You may want to bring a Tactical Insertion because other players may discover you on your way to the top, or while you are up there, and lob grenades.

"Highrise": Get on roof

Spawn on the side with the big "KREIGLER" letters. Go to the other side of the "KREIGLER" letters. You will see a hanging window washer container. Jump off the map towards the container, and land on it as if it wa ladder. Wait for a moment and make sure your character is attached to the container. Move up (as if climbing a ladder), then walk on the scaffolding to the other side of the building. Jump into that container, then onto the roof. You have now successfully made it to the roof. It is best to have a tactical insertion when playing in multi-player mode.

"Loose Ends": Blow-up doll

Start the mission and continue all the way until you get to the first building. Once clearing the entire first floor of enemies, make your way upstairs to breach the doors. Breach all doors on that level until you get to the last door to breach on that floor. Once you squad has announced all clear, make your way into the bathroom, which should be to the right of the room as soon as you breach it. Look into the bathtub and you can see a blow-up doll with colorful stars on its chest and a circular mouth.

"Loose Ends": Infinity Ward teddy bear

Once you enter Makarov's safe house, go upstairs and look to the right. There will be a bathroom. You will find the Infinity Ward teddy bear pinned to the wall with a knife.

"No Russian": Quick completion under Veteran difficulty

Successfully complete the "No Russian" mission under any difficulty setting. Select it again from the mission menu, and choose the Veteran difficulty setting. After the level begins, pause game play. You will get an option to skip the mission due to its content. Choose to do so, and you will be given credit for completing it under the Veteran difficulty setting.

"No Russian": Random death

When you get to the end of the level where the back of the ambulance doors open, go to them as usual. As soon as they open, run away. Immediately after Makarov says "No, this is the message", you will randomly die.

"O Cristo Redentor" Spec Ops mission: Easy completion

Follow this pattern to easily complete the "O Cristo Redentor" Special Ops mission under the Hardened or Veteran difficulty setting. For every ten defeated militia, two dogs will attack you. Typically one will appear from the high ground behind the fence, and another from the west. For every ten defeated men, run to the white truck near your starting point. Jumping on top of this truck will trigger the dogs to freeze wherever they stand. Lure them by standing on the ground. When you hear their barking get near, leap onto the truck when they are in the vicinity. Now that they are frozen, you can pick them off wherever they stand.

"Rust": Invincible pipe

At one end of the map is a short length pipe sticking out. If you climb in it, you cannot be killed by kill streak explosions (for example, air strikes, Predator missiles, AC-130, etc.). The only time it can kill you is if it goes directly into the pipe.

"Terminal": Easy kills

Enter the plane, either going up the raft-like object or from the hallway inside the building. Go to the front, where the pilot would normally sit. Crouch in the left corner against the wall so no one can kill you through the windshield. If someone else comes in the front without noticing you, knife them. Otherwise, just shoot the people you see in the hallway coming to the plane. Never look through the doorway. If you do and there is someone there, they will shoot you and most likely you will not have enough time to react.

"The Hornet's Nest": Infinity Ward teddy bear

Select Campaign mode and play "The Hornet's Nest" in Act 2. Go to the market and look for a soccer ball on a table to the left. Walk a short distance ahead to find a television set. Break its screen to find an Infinity Ward teddy bear inside.

"Wasteland": Easy kills

Go to Wasteland on a online multi-player game with a Sniper class set up. The Pavelow, an air strike of any kind, and sentry gun is recommended, along with the thermal scope and tac. insertions. Go to the area where the house is next to the graveyard. Do not go in the house. On the opposite side of the house away from the graveyard is a white wall with a mounted machine gun. Crouch behind the wall and move around until you can just barely see over it. Watch the area around the house. Enemies will frequently run by. Pick them off as they do. You can get enough kills for kill streaks, then let them do the rest.

Doing so will skip the level, but will still award you the completion on Veteran difficulty, as though you had played it through to the end.

Call Of Duty reference

Go to a private match online, or splitscreen. Choose the multi-player map "Terminal". Go to the match set up and change the rules to the following: Spectating (Free). Once done, start the game. Then, go to Spectator mode. Fly your camera to the top of the escalators near Burger Town restaurant. Once done, face the Burger Town restaurant and look to the right. You should see about four orange cones, a trash can, two benches, a table, and other objects blocking the other half of the terminal. Fly your camera over those items. Once done, face in the direction of Cherubini's. From there, look to the right. You should see a store named "Pete's Candy Shop." Go inside Pete's Candy Shop. You should see two Xbox 360 Call Of Duty games just floating to the left of the chocolate sign.

Chicken out prestige

Once on the information screen, select "Continue" and it brings you to a screen with "There's no going back..." Press [Back] and chicken sounds effects will be played, as if Activison is making fun of you.

Cooking grenades

Custom class slots

Reach the indicated Prestige level to unlock the corresponding Custom class slot.

Six total custom class slots: First Prestige.
Seven total custom class slots: Second Prestige.
Eight total custom class slots: Fourth Prestige.
Nine total custom class slots: Seventh Prestige.

Defeating Juggernauts

The most difficult way to do this is to unload on them with your frags, stuns, and ammunition, but even then they do not always die. There is an easier way if you have a Thumper. Try to hit them in the head with it. This strategy is still difficult, but you can conserve ammunition. If you cannot seem to hit them with the Thumper, an even easier way is with a sniper rifle. About three to four shots in the head will take care of him. Almost every Special Op with a Juggernaut also has a sniper rifle.

Easy Cold Blooded Pro perk

Create the following class:

Primary weapon: Any light machine gun (except AUG HBAR) with extended magazine attachment (optional).
Secondary weapon: A launcher (not the Thumper or RPG7x2) that can heavily damage a Pavelow.
Equipment: Tactical insertion.
Special grenade: Your choice.
Perk 1: Scavenger.
Perk 2: Cold blooded.
Perk 3:Your choice.
Death Streak: Your choice.

After you make this class, host a private match or a split-screen match. Make sure that your friend has a class with Hardline, and the Pavelow as one of their Killstreak rewards. Allow your friend to kill you enough times until they have their Pavelow. When their Pavelow is out, use your rocket launcher to hit it. If it is not destroyed the first time, use your Scavenger perk to get more rockets. Immediately after the Pavelow starts to spin out of control, take out your light machine gun and rapidly shoot at it. Each bullet that hits the spinning Pavelow will count a toward Cold Blooded Pro. By doing this, you can easily earn Cold Blooded Pro within a five minute match.

Easy Last Stand Pro perk

Create the following classes:

Class 1
Primary weapon: Your choice.
Secondary weapon: None.
Equipment: Tactical Insertion.
Special grenade: Your choice.
Perk 1: One Man Army.
Perk 2: Hardline Pro.
Perk 3: Your choice.
Death Streak: Final Stand.

Class 2
Perk 3: Last Stand

Note: Also make this class built to quickly kill your enemy.
After you make those classes, to host a private match or a split-screen match. Make sure that your friend is willing to be killed multiple times. If no one is willing, then use an empty player (a controlled player with no one actually controlling it). Start with Class 1. Allow your friend to kill you until Final Stand is activated. Have your friend shoot you into Final Stand. Once you are in Final Stand, activate One Man Army and switch to your second class. After you get up, start killing your friend. Every kill you get will count as a Last Stand kill. Every kill will also count toward One Man Army.

When in combat and you need to reload, it is much faster to switch to a pistol or shotgun.

After you get the riot shield and leave the room where you got it, turn left, and go down the hallway. In the first open cell on the right-side wall is the Intel on a desk.
Once you find the person you have been looking for, turn to your left to find the Intel on the desk.

Act 2: Of Their Own Accord
Inside the elevator that keeps trying to close (in the hallway after you enter the building), the Intel is to the right of the body sitting inside.
In the room with a balcony (out on the balcony is a missile launcher), go to your left as you enter the room, and enter the door straight ahead (near the portrait of Franklin Pierce) to find the Intel on a table down a small hallway.

Act 3: Contingency
When you reach the three-man patrol standing near the fence, kill them, and go over to where they were. The Intel is about ten feet south on a crate.
The building labeled "33" along the angled south-west fence contains the Intel on a metal desk inside the northern door.
Just north of building "33", locate the stairs leading to a helipad (has blue lights on the corners) to find the Intel in the north-west corner.

First, go online and set your killstreaks to one or more of the following: Care Package, Sentry Gun, or an Emergency Airdrop. Then, go into a session and get the killstreak. Once done, get into a good hiding spot. Throw your red smoke grenade (killstreak) somewhere where you will be able to see it. Then, wait for an enemy to attempt to steal your killstreak but miserably fail. Alternately, if you have unlocked claymores, you can throw your red smoke grenade (killstreak) and set a claymore by it. It is a good way to get a lot of points.

Museum bonus level

When you have completed the game, go to the single player missions. Select the bottom new mission, called "Museum". When you start the level, the best thing is to study the layout. Get two weapons and top off the ammo with the crates supplied. Go to the desks by the entrance to the rooms. Note: There are three rooms, one of which nothing happens. On the desks there is a red bell that is labeled "Don't Press". Once you press this button, the entire museum comes to life in one room area at a time. About thirty people (all characters from the game) will try to kill you. Choose a difficulty at the start. You will hear a sound once that wave is done. There are two waves of kills needed to complete it. Do not shoot anyone prior to using the bell, as it will not count.

If you are looking for the ultimate Noob Toob class then set something up with the following.

Assault rifle with grenade launcher.

Plane

Ok you need to play on terminal with a friend on the opposite team and to use a class with comando, and tac knife. Go up the plane on the side and look through the window on the right. Your friend should be against the wall farthest a way. Then you should be parallel then try to stab him through the window and you'll appear on the plane.

Portal reference

In multi-player mode, there is a "title" you can get called "Companion Crate". You can get it by calling in a Care Package (and perhaps the emergency drop as well) and letting a teammate get it. This seems to be a reference to the companion cube in Portal.

Raising prestige

When playing online, the first time before you prestige is basically pointless. Any progress you made with any primary, secondary, or any other weapon or kill streak will be reset. However, after you prestige the first time, the kills and headshots you get with your primary and secondary weapons, except the riot shield, will be saved via the Master and Veteran challenges under each gun. After you prestige once, you will also get the Prestige challenges, which is a separate set of challenges like Basic Training, most of which will remain if you prestige again. This tip will help not wasting hours maxing out a gun the first time to get nothing and only to learn that you have to do it again.

Riot shield defense

While the riot shield is equipped to one of your classes, you can have defense from the rear when you are holding your secondary weapon. You can now change the direction of defense with your riot shield. This is useful in narrow corridors and stairwells.

Sixth custom class slot

Reach level 70 in Multi-player mode then enter Prestige mode.

Sniper camouflage

Complete the Ghillie In The Mist challenge with the following results to unlock the corresponding Ghillie camouflage suits for Sniper classes.

Arctic camo: 50 one-shot kills with sniper rifles.
Urban camo: 100 one-shot kills with sniper rifles.
Desert camo: 200 one-shot kills with sniper rifles.

Spec Ops Juggernaut message

Play multi-player Spec Ops mode. Go to a level where a Juggernaut can be found. Have yourself or as partner walk up to him and get into last stand (bleed out). Look at the Juggernaut's crotch area to see the message "Get sum!".

Stimulus Package: Bailout: Call Of Duty: Modern Warfare reference

Start a Private match and find the indoor arcade with the tilted televisions and staircase. Locate the bathrooms across from the vending machines and look off to the right. You will see an arcade game labeled "Modern Warfare" (a reference to Call Of Duty: Modern Warfare). If you look to the bottom of the machine you will see an 8-bit version of Captain Price that is styled the same way as Mario (from Super Mario Brothers). The differences include Captain Price's distinguished muttonchops, hat, and clothes.

Top of Plane in Scrapyard

First you need to go to the delivery truck next to one of the plane scraps. Then climb on top of the truck through the front. Sprint and jump and land on the side of the plane. Jump again and you will be on top of plane.

Trailers

Allow the game to idle at the main menu. Trailers for the game leading up to its release will begin after a few minutes.

Transformers reference

There is a Challenge listed under "Finishing Moves" named "Transformer", where a player must get a Game Winning Killcam with a Pave Low. This challenge is a reference to the helicopter Transformer "Blackout" in the first segment of the Transformers (2007) movie.

Unlimited claymores

Put on the Scavenger perk and use claymores. You can put one down and when it kills someone you can scavenge his body for another. You can also scavenge when you already have one down, get another, and place it somewhere else. You can only carry one at a time but you can put down as many as desired. It works best to hold up in a room. Every time someone comes through it goes claymore, scavenge, set, and repeat.

Unlimited grenades

When using the One Man Army perk, equip a grenade launcher to one of your guns. After you run out of grenade, use One Man Army, select the class you were just using, and you will have two more grenades for the tube. Also, everything else will refill. Repeat this as many times as desired.

Using teammates

You will almost always have several allied team members on your side throughout the game. The teammates that are invincible are Dunn, Ghost, Foley, Makarov, MacTavish, and Price. Always let them lead the way during battle. While your other teammates can die, they will usually be replaced by reinforcements. Although it is slower, it is much safer to let your teammates lead the way, especially when you are low on health and need to heal.

Various game references

Go to any Private, Ranked or Split-screen match on the Estate map. Pick up a Sniper (or any telescopic sight weapon) class, and when the game begins, go inside the estate (the largest house in the center of the area). Look in the rack under the LCD television in the main hall. There should be a Gamestation 5 console (reference to the PlayStation) with several games named "Italian Plumber Princess Rescue" (a reference to the Mario games) and "Deer Hunter 17" (a reference to the large quantity of Deer Hunter games).

Also in the estate, go to the basement via the stairs in the kitchen. Look at the posters in the wall around the pool table. There should be one with the name "Massey Effect" (a reference to Mass Effect) and in the same poster, there should be the description "Chaos Theory was just the beginning" (a reference to Splinter Cell: Chaos Theory, which story is considered the start of the subsequent Splinter Cell games' stories).

X-Men: Last Stand reference

There is an achievement called "I'm The Juggernaut...", which is awarded for killing a juggernaut in Special Ops. This is a reference to the movie X-Men: Last Stand, where the Juggernaut is trapped in the floor and yells I'm the Juggernaut bitch".
