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.

Taking down guys with riot shields
When they are standing up shoot at their feet if they are crouching either throw a grenade or a flashbang or run up melee them and shoot while they are one the floor
Submitted By: game chicken
Chicken out prestige
Once you have ranked past 70, go into the prestige where it tell you what you will gain and lose. However, do not actually 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.
Easy "Unnecessary Roughness" achievement
In the "No Russians" level, when you kill the SWAT with the riot shields just pick one up and kill anyone else you find alive.
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.
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!".
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.
"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.
"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.
"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.
Make a trap
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.
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.
Cooking grenades
Hold your grenades for two seconds before throwing them. This will prevent enemies from having enough time to throw them back at you.
Faster reloads
When in combat and you need to reload, it is much faster to switch to a pistol or shotgun.
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.

Act I: S.S.D.D.
1. The Intel is under the watch tower, straight across from the entrance to the obstacle course.

Look for a small wooden fence surrounding some trees in the middle of the path in front of you, and a small wooden building up a hill to the right.

15. Near the beginning, after you move forward from the first building, go inside the house to the right of where Soap stops in the road (there is a blue car in the garage). Go past the blue car and into the kitchen to find the Intel on the table.
16. After clearing the small lot (has a bunch of appliances and cars), instead of going right up the stairs between buildings, go left around the three-story house (floors are colored red, yellow, red), and look in the little hut attached to its side to find the Intel on some barrels.
17. As you move up the sloped street, there is a blue car on the right side of the street. In the building on that side is the Intel up on the second floor on the table.
18. When you enter the last open lot and are supposed to go up on the roof, turn to the right, and look in the window behind the goal fence to find the Intel inside a window.

Act II: The Gulag
25. As your team moves towards the arch with the red light, go to the stone stairs before it, and look inside the room on the far wall to find the Intel on some filing cabinets.
26. The Intel is on a desk behind the large wall of monitors you encounter on your way through.
27. 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.
28. Once you find the person you have been looking for, turn to your left to find the Intel on the desk.
Act II: Of Their Own Accord
29. 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.
30. 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 III: Contingency
31. 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.
32. The building labeled "33" along the angled south-west fence contains the Intel on a metal desk inside the northern door.

Act III: Loose Ends
36. Before entering the house, go behind it, and locate the small boat hanger along the shore. The Intel is on a crate outside of it.
37. In the locked room on the top floor of the house, the Intel is on a desk in front of the door.

39. The Intel is immediately to your right when you begin the mission, in the front of the plane.
40. After you slide out of the plane hull and move across the street and up the hill, look for the plane pointing towards the road. The Intel is inside, near the cockpit.

Call Of Duty: Modern Warfare 2 Items
Easter Eggs
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.
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).
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".
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.
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.
KFC reference
There is an achievement named "Colonel Sanderson", which is awarded for killing ten chickens in seven seconds on "Hornet's Nest". This is a reference to Colonel Sanders, the founder of KFC.
Glitches
"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.
