- Call Of Duty: Modern Warfare reference and 8-bit Captain Price in 'Bailout' map ('Stimulus Package' DLC)
Begin 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). Look at the bottom of the machine to see an 8-bit version of Captain Price that is styled the same way as Mario (from Super Mario Bros.). The differences include Captain Price's distinguished muttonchops, hat, and clothes.

- Easy level boosting with riot shield
Get twelve people in a lobby, and explain how the level boosting is going to work. Next, kick six people out so there are only six in your party. Then, find a Search And Destroy game. Notice: While trying to find the game, make sure the host (the person trying to find the game) temporarily has a bad connection so it will make you host the lobby and not pair you with someone else. Once you are in the lobby, you can invite the other six people to join. When all the spots are filled, you can make your connection good again and begin the match. Choose a class with the riot shield. It is recommended both players use the One Man Army perk if you have unlocked it. Once the match begins, find another player, and have them keep shooting you while you keep pushed the riot shield to block the bullets. You will get +500 experience points every few seconds five times. Once you begin only getting +100 experience points, switch classes and have the other player switch to a riot shield class. Do the same things to them until they only get +100 experience points, and then switch back. Repeat this as many times as desired. It is possible to get over 50,000 experience points per match if done correctly. Notice: To keep the game going as long as possible, make sure one team plants the bomb and then the other team defuses it.

- Hidden sniper positions in 'High Rise' map
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. Find the broken scaffolding. Sprint from before the ledge, and jump to the left outside yellow vertical railing of the scaffolding. 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 moving forward to reach the roof. This is a very good sniper spot. It is recommended you use a Tactical Insertion because other players may discover you on your way to the top, or while you are up there, and try to kill you. There are also a lot of teddy bears on the roof.







- X-Men: Last Stand reference
The 'I'm the Juggernaut...' trophy is a reference to the X-Men: Last Stand movie, where the Juggernaut is trapped in the floor and yells 'I'm the Juggernaut!'.

- Easy 'Armor Piercing' mission in Special Ops mode
When the mission begins, grab the Barrett .50 Cal and/or Intervention. Then, keep running up the stairs until you reach the scaffolding (there is an ammo crate below the scaffolding). You may encounter a Juggernaut near the scaffolding. If so, kill it, and then climb up the scaffolding. Go prone, and just try to keep sniping the Juggernauts straight ahead with the Barrett .50 Cal or Intervention. You can also have one player hide behind the ammo crate below the scaffolding and try to lure them towards you. Alternately, have one player die on a staircase to block the path of the Juggernauts, while the other player kills them from behind it.




- Easy 'Downed but Not Out' trophy

You can also scavenge when you already have one setup, then 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 stay in a room. Every time someone comes through it and gets killed, scavenge, set, and repeat.

- Various game references
On the Estate map, go inside the estate (the largest house in the center of the area). Use a sniper rifle, and look on the rack under the LCD television in the main hall. There is a Gamestation 5 console (reference to the PlayStation) with 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). Go to the basement using the stairs in the kitchen. Look at the posters on the wall around the pool table. There is one with the name 'Massey Effect' (a reference to Mass Effect), and in the same poster, there is a description 'Chaos Theory was just the beginning' (a reference to Splinter Cell: Chaos Theory, which is the story considered to be the beginning of the subsequent Splinter Cell games' stories).

- Museum bonus level
Successfully complete the game to unlock the Museum bonus level. Go to the single player missions, select the new 'Museum' mission at the bottom, and choose a difficulty. When the level begins, it is recommended you first study the layout. Get two weapons, and max out your ammunition through the crates supplied. Go to the desks by the entrance to the rooms. On the desks there is a red bell that is labeled 'Don't Push'. Once you press this button, enemies will begin coming to life in one room area at a time. About thirty people (all characters from the game) will try to kill you. You will hear a sound once that wave is completed. There are two waves of kills needed to complete it. Notice: There are three rooms, one of which nothing happens in. Do not bother shooting anyone prior to using the bell, as it will not count.

- Easy 'Drive By' trophy
Play the 'Race' mission in Special Ops mode on Solo Play. Just keep shooting enemies on snowmobiles while driving to get the 'Drive By' trophy.




- Hidden face on sniper lens cover
In Multiplayer mode, keep pushed any sniper rifle with its primary scope. Begin running in any direction, as long as the sunlight shines on the back of it, to see a green frowning face with its tongue sticking out, like the one you can receive in your accolades.

- Shepherd comments in 'Endgame' mission
At the end of the final 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. When 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. Notice: If you get too close to Shepherd, he will knock you against the car. If you are too far away, he will cut the speech short.

- Invincible pipe in 'Rust' map
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.) unless it goes directly into the pipe.

- Easy 'High Explosive' mission in Special Ops mode
Notice: This trick requires two players. When the mission begins, run to the left, and look down the alley. If there is a Juggernaut standing there, either try to kill him or stun him so you can both enter the building on the far left through the large window. Have one player stand in front of the doorway, and die while trying to shoot at the Juggernauts. Have the other player crouch behind the table next to the large window you entered through, and simply shoot the Juggernauts as they stand near the door. They will not be able to get past the player downed in the doorway. Make sure to revive the player after killing the Juggernauts standing near the doorway so they do not bleed out. The Juggernauts usually come in waves of 1-1-2-3-3. If you get a chance, you can refill your ammo near the area you begined the mission.
