- Secret Lab
When Jung must hack the computer to open the door to Irena, enemies rappel down from the windows. Before you tell him to hack, send your team to the far side of the room over near the fenced area. Then, run behind the computer and tell Jung to hack it. A trigger will activate and the enemies will begin pouring into the room. Your team will take most of them out on the way to the computer. If someone on the team goes down, Jung will stop moving towards the computer and sit there (or Michael, depending on who goes down). Once there is a pause in the battle, tell him to heal your partner. You can then order them around as usual. During this time, Jung was supposed to be hacking the terminal, but killing all the enemies skips this part. Once done, tell Jung to hack it again. He will open the door to Irena. Michael will get left behind. Watch yourself; there are enemies on the stairs above you and will pick you off as you come up, especially on on the Realistic difficulty setting.

- Shoot grenades
To perform this trick, take cover against any wall. Make sure your weapon is on single shot, then fire one blind shot. Keep pushed LT + RT, then push and release B. A grenade should shoot about 20 to 30 feet around the corner. Notice: This works with all grenades except for C4 and breaching charges.

- Bypass Irena in Single Player mode
If you have failed the mission trying to defeat Irena, you will have to reload the checkpoint. When you do so, it will spawn you in a hallway. There should be a door to your right and another a short distance down the hallway. Use the door that is on your right when you spawn. When you open that door, the computer that needs to be hack will be directly across the room from you. Kill all of the terrorists, but do not assign a team member to hack the computer. Face the back of the computer, not the controls, and turn right. You will see a set of stairs. Walk up those stairs very slowly (try crouching), and you should be able to ease your way past Irena without her seeing you. When you pass all of the glass windows, you will see a metal door. Make your way to that door and 'Saving Game' will appear. Once that has happened, just run back past Irena and it will cause you to fail the mission. However, when you reload checkpoint, the metal door will be open for you.

- Easy Count Down level
In the Count Down level in Xbox Live Multiplayer Co-Op mode, walk towards the elevator door. Keep pushed LT, release, then push Left Analog-stick Forward. You will walk through the elevator. Run upstairs (wearing no armor for more mobility is recommended). Go towards the missile truck, and walk a little behind it. Keep pushed A to interact with it and hide. You will win without the enemy respawning and gain 50 experience points.

- Camera
If you are having trouble capturing your face for your custom character or you are getting a message saying the picture is invalid, try the following:


- Big heads
Pause the game in Single Player mode, then keep pushed LB and press B, X, A, Y, click Left Analog-stick, press Y, A, X, B, click Right Analog-stick.

- Get on high roof and fenced off area in Calypso Casino
This trick requires you and a friend/squad member on the Calypso Casino multiplayer map. Make your way up the stairs towards the helipad where you must bring the Intel on an attack and defend mission. Once you reach the top of the stairs there should be two boxes overlooking the top floor where you can take cover behind. Go to the very first box closest to the stairs. Push Cover about two or three times at the right corner of the box then keep pushed Cover. You should now be floating in the air. Do not move until your friend runs up behind you and runs into your back. When your teammate is running into you, begin pressing Forward and he will 'push' you on top of the box. Once you are on top of the boxes, there should be a railing next to you. Walk onto the railing then run towards the stairs and the railing should lead you around a previously fenced off area where you can drop down into and cover all three entrances to the helipad if your team is defending the Intel on the helipad. To continue, keep running on the railing past the fenced off area. You should be running towards the roof that connects with the elevator building. Run to the very end of the railing then run onto the roof. You now have complete coverage of the entire roof area of the map. It is recommended that you either watch the repels or elevator door if you have an SMG/rifle, or watch the far repel if you have a sniper rifle. If you only have a shotgun do not bother going up there.

- Getting the Veteran Hunter and Elite Hunter achievements
The Veteran Hunter and Elite Hunter achievements are glitched. The way to get these achievements is to play T-Hunt in single player mode and not split-screen. Also, you can get both achievements at once just by completing all the maps on the Realistic difficulty first instead of both Normal and Realistic.

- Get on top of the roof in LVU Campus
This trick requires at least two people. Make a match with two slots and a private slot. You can do this with any amount of people. Invite a friend and send him a private chat invite. Ask him to meet on the roof of the spawn where the fast roping skylight is located. Have him stand in the middle between the air conditioner vent and the ledge on the far left of the entrances to the roof. Keep pushed LT + Left Analog-stick Up in front of the vent. Release LT and keep keep pusheding Left Analog-stick Up. Release Left Analog-stick Up and you should be on top of the vent. Walk over your friend's head. Notice: Your friend must be crouched. You should be on top of the ledge of the roof. After you are on the roof, make a right and go forward. Then, make another right until you reach the middle office room. Stop, then align yourself with the left edge of the small building. Jump off then walk in a straight line until you reach the end of the path. Turn to your left and you should see the overhead of the left catwalk/bridge. Align yourself with the edge of the overhead then walk forward. You should be on top of the overhead. Keep walking straight until you are at the edge of the overhead. Align yourself with the low concrete wall, then jump off. Follow the low wall until it ends by the stairs. Align yourself with the low wall below the edge near the light post, then jump off. Turn to your right where there are an abundant amount of plants and trees. Walk towards them. Keep walking on the sides of them. With the correct camouflage you can hide from the enemy and attack when they are close.

- See through any door
At any door, have another player get in front of it. Once they are in position, turn on your thermal vision. Then, get behind your them. Look through the icon that is above his or her head. You can now see through the door. You will be able to see if there are any terrorists behind the door. Notice: If playing any adversarial games, your friend must be on your team.

- Co-op single player mode weapons
In single player Co-op Story mode, some of the guns unlocked in Career mode will not be not accessible (for example, the Desert Eagle and SPAS 12); however, the terrorists in Co-op Story mode will use them. To unlock those weapons, play a mission in multiplayer Co-op mode. Pick up the terrorists' guns that are left behind after they die. Finish the level with them to unlock them at the equipment menu. You can unlock the SPAS 12, Desert Eagle, and MG36.

- Outtakes
Play the Fremont Street level and look for a ledge that has a bottle of Axe cologne. Shoot the bottle and the neon roof of the Fremont Street Experience will change to an animation of a girl in a bikini with some Axe items. This is followed by a sequence with outtakes and early animations.

- Splinter Cell: Chaos Theory reference
In the Dante's Casino level near the arcade, there is a machine labeled Tom Clancy's: Splinter Cell: Chaos Theory.

- Easy entry in Exclusive Gone Wrong
When the mission begins, make your squad rappel down the left part of the building. Then, order them to go down until they are able to breach. Next, go to the middle of the roof with the opening. Drop a C4, incendiary, smoke, or frag grenade, and keep shooting through the glass. After a few seconds, order your squad to breach into the building. Finally, rappel down into the building.

- Look into other building in LVU Campus
Go to the roof of the LVU Campus level. There should be a ventilation unit to the far left when you come in from the staircase doors. On the vent is a little fuse box. Take cover directly on the fuse box and press Forward. If done correctly, you should now be on the vent. Have another player stand between the vent and the closest edge of the roof. Walk over him and onto the edge of the roof. You can now see over the outside of the campus and into the other building.
