From Alpha spawn, stay on the bottom floor and walk out to the double doors. Once you get out, look to the right and there will be a fence. To get over it, follow the fence to the palm tree at the end and tell a friend to take cover on it. Once he does, tell him to get off and walk to the left a short distance. Here, you should be able to take cover in mid-air. Tell him to look out to his left as far as he can, then have your player go to the side of the palm tree facing the fence. Back up slightly and you should be able to take cover in mid-air also. As your friend looks to his left as far as he can, lean out to your right, into your friend. Then, release everything and walk forward, over your friend's head and directly into the palm tree. Walk into the fence along the top of the fence and move back to the Alpha spawn double doors. When you get to that wall, back up slightly and tell your friend to crouch and take cover on the wall and get as close to the fence as possible. Walk onto his head and tell him to stand up. This should boost you up and over the wall. If you do not get the palm tree glitch the first time, keep trying as it sometimes requires several attempts.
Enter the room that separates the security offices from Bravo spawn--this room is usually called the "broom closet". Find a bucket sitting in front of a cart just before you get to the security offices. If you try to take cover on the bucket, it should force you to take cover on the cart. When this happens, look up and over the cart, then release LT and walk forward. You should then be on top of the cart. If you stand up, you will be able to see upstairs through the ceiling. This is useful to watch for approaching enemies, you can toss grenades, and you cannot shoot through it. If an enemy sees you, crouch back down or he will shoot you in the head.
If you have fail the mission trying to defeat Irena, you must 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 hacked will be directly across the room from you. Eliminate 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 to see a set of stairs. Walk up those stairs very slowly (try crouching) 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 easily and "Saving Game" will appear. Afterward, 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.

OPA Observe: Locate nearby enemies by taking cover, or by using your snake cam to peek under doors.
Plan: Use the Tactical Map to help you identify all entry points. Use the snake cam to prioritize targets for your team to neutralize first.
Assault: Order your team in. You can more efficiently assault a room by entering simultaneously through an alternate point of entry.
Frag & Clear Order your team to throw a high-explosive fragmentation grenade when dealing with tight groups of enemies. The flying shrapnel produced by this grenade is usually enough to neutralize enemies within a large area. After it explodes, your team will move in to eliminate any surviving terrorists.
Breach & Clear Use a Breaching Charge when dealing with terrorists standing close to a door. It will stun everyone inside the room so you and your team can safely clear the room.
Flash & Clear: The Flashbang Grenade produces a blinding flash and a defeaning blast. It temporarily confuses and disorients potential threats, making this a non-lethal tool that's especially effective for hostage scenarios.
Smoke Grenades A Smoke Grenade can cover your movement when Terrorists have you pinned down. Use your Thermal Vision to see the enemies' heat signature through the smoke and neutralize them.
While playing multiplayer co-op mode, walk towards the elevator door while holding LT. Then, release it and press Left Analog-stick Forward. You will walk through the elevator. Run upstairs (wearing no armor for more mobility is recommended) and go toward the missile truck. Walk a little behind it, then hold A to interact with it and hide. You will win without the enemy respawning and gain 50 experience points.
Go to the roof of the LYU Campus level and find the 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 will be on the vent. Have a friend stand between the vent and the closest edge of the roof, then walk over him and onto the edge of the roof. You can now watch over the outside of the campus and into the other building.
Walk to the left side of the building with the fast ropes from the roof to see a large cork board. On this board you will notice a poster advertising Assassins Creed. Note: This advertisement on this poster changes with Xbox Live updates. Take cover with your back to the poster three times during terrorist hunt. Have a friend crouch in front of the left door to the teachers office up the stairs behind you and open it. Even though the doors do not actually open, you can still see through it as if it was. This lets you see if any terrorists are inside. This is very useful for breaching charges and C4, giving you very easy completion of this level. You can lurethe terrorists to this door once you get down to eight remaining.
Have a friend with you and go to a door. Once at the door, have your friend get in front of the it. Once your friend is in position, turn on your thermal vision and get behind your friend. Look through your friend's icon that is above his or her head. You can then see through the door and can see if there are any terrorists behind the door. Note: If playing any adversarial games, your friend must be on your team.
Before making Jung hack the computer, send your team to the far side of the room near the fenced area. When the enemies pour in after you tell Jung to hack it, your team will take most of them out. Be careful with Michael when he gets left behind, there are enemies waiting on the stairs above.
Once you begin the mission, make your squad rappel down the left part of the building and order them to go down until they are able to breach. Then, go to the middle of the roof with the opening and drop C4, incendiary, smoke, or frag while repeatedly shooting through the glass. After a couple seconds, order your squad to breach into the building. Finally, rappel down into the building.
Load a multiplayer game that takes place in the Calypso Casino and walk up the stairs where the helicopter is located. Go to the to boxes that are there and take cover at them while standing up. Aim your gun to the right, then release RT and the Left Analog-stick . You should now be flying. Click the Left Analog-stick so you are standing, then walk on the box.
-At least two people are required for this glitch. Make a match with two slots and a private slot--this is possible 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, then have him stand in the middle between the air conditioner vent and the ledge on the far left of the entrances to the roof. Hold LT +Left Analog-stick Up in front of the vent, then release LT and keep holding Left Analog-stick Up. Release Left Analog-stick Up and you will be on top of the vent. Walk over your friend's head. Note: Your friend must be crouched. You will be on top of the ledge of the roof. After you are on the roof, make a right and go forward before making another right until you reach the middle office room. Stop, 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. Proceed 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, then walk toward them. Keep walking on the sides of them. With the correct camouflage you can hide form the enemy and attack when they are close.
-Go to the roof with a partner and get in cover on the box on the right of the roof. Look up all the way with your weapon also pointing up to go on top of the box. Have your partner stand to the left of the box, crouching in the middle, then walk over your partner and you will be on top of the roof. You will now be free to walk around out of the level's boundary.
This trick requires two players. Begin a game with 20 rounds for 20:00 minutes with 15 between matches. Use a rubber band to position both Analog-sticks so that you walk in circles to earn 800 points for a game, which will gradually decrease over time.
To unlock the SPAS 12, Deagle or MG36 in Single-player and Co-op Story mode, play a mission in multiplayer co-op mode and kill a terrorist armed with one of them and pick it up. Complete the mission with the guns to unlock them at the Equipment menu.
The "Veteran Hunter" and "Elite Hunter" achievements are glitched and thus can be unlocked by playing T-Hunt on single player mode and not split-screen. Also, you can unlock both achievements at once just by completing all the maps on the Realistic difficulty first instead of both Normal and Realistic.
A friend/squad member on the multi-player map Calypso Casino is required for this glitch. Make your way up the stairs toward the helipad where you must bring the Intel to on an attack and defend mission. At the top of the stairs there are two boxes overlooking the top floor where you can take cover behind. Go to the very first box closest to the stairs. Press Cover about two or three times at the right corner of the box, then hold Cover. You should now be floating in the air. Do not move until your friend runs up behind you and runs into your back. While your teammate runs into you, start pressing Forward and he will "push" you on top of the box. Now that 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 proceed, 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. You should 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 have a shotgun do not bother going up there.
