- 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.

- 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.

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).

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.
