EA formation - Unlock the Frag Grenade weapon challenge, then successfully complete all rounds and kill all enemies through round ten. If every enemy is killed, you will go into round eleven. In this round, the soldiers move and create the shape of first an "E", then an "A" as a reference to EA Games.

Get two helicopters easily in Air Traffic Control level - At the beginning of the Air Traffic Control level, you will start out as a sniper. Directly behind you will be a chopper. Turn around as soon as the level begins to get a good shot. Shoot the pilot and the chopper will fall a short distance directly in front of you. Make sure you hit the pilot, and not the chopper or it will explode. Note: It may require a few attempts to hit the pilot. You can then get in and shoot out the turrets with the chopper. When the jeeps come by, hotswap to one and go directly past the turrets and into the helicopter inside the heliport. You will not have acquired two helicopters, making this level very easy.

Hotswap Challenge - When doing the Hotswap Challenge, it is easier if you move towards the marker to make more "Hotswaps" available. By doing this, you will not lose 1,000 points.

RPG Rocket Challenge - When doing the RPG Rocket Challenge, the further you are away when you blow a vehicle up, the more points you get. An easy way to get points is to take a vehicle's shield down at close range, hotswap to a further away RPG man, then finish the vehicle off.

Duck, Cover and Aim - In any level of the game you may have trouble aiming and staying out of the way of the enimies fire. To get out of fire you can duck, and then lay down by pressing the button again. Ducking also improves your shot accuracy, laying down helps even more. To get out of laying down fast just press the button again and you will get up right away.

Vehicle Bomb - First put a C4 on a Jeep/Humvee and make sure nobody else gets in the jeep but you. Then drive the jeep fast until you find an enemy. Before you get to the enemy jump out of the vehicle, and when the vehicle rolls over to the enemy detonate the C4. You can blow up people and other vehicles easily and get lots of points and kills.

Get Flags Easier - On the level, Strike At Karkand, be the Americans. Go to the first flag, and on the side that is closest to where you originally spawned, you will see a ladder. Go up the ladder to get to the flag instead of going out in the open to go up the stairs. This will give you the element of surprise and help you capture the flag easier.

Get Cheap Medals on Backstab - First, you have to be playing multiplayer online on Backstab. Go over by Flag 4. You will see a car on fire. Have one of you teammates jump in the flame until his health is half-way down. Then heal them. Repeat to get a medal every time!

Online Help - A good map to learn the ropes of the online mode is the map "Backstab". In this map there is a very good sniper point, it is very helpful for getting kills without dieing and it in turn helps you obtain medals. It is located near flag 3. Run west from flag 3 and you should get on to a road almost parralell to the road which flag 3 is on. In this street there is a door in the wall and if you go inside it you will see another door, although this door has been boarded up. To remove these boards shoot them or blow them up. Then run up the stairs and you will see some archways and you will have a clear view of flag 4 and flag 5. i recccomend you crouch down right beside a pillar on the balcony as it blocks off most view points of you.

Stay Alive Longer - It's not a cheat but it helps you alot in levels. If your about too die you can switch with a Sniper, Special Ops, ETC. If your in a car and the COMP. isn't shooting very well, you can press TRIANGLE and switch to the gunner. Same with a tank.
