All weapons - Enter during play
Code Effect - Hold L2 + R2 then press Right(2), Down,
Up. Left(2) All weaponsEA 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.
Avoiding missiles - When flying a
helicopter in Multiplayer mode, if you start to get laser targeted
(not GTAM), fly as fast as possible, and at the same time get as
low to the ground as you possible. If done correctly, the missile
will hit the ground and miss you most of the time.
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.
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.
Get under buildings - In "The Nest" map in Conquest
mode, go to flag 4. Drop down the side of the building and stay
close to the wall so you do not slide down in between the
mountains. You will see two windows on the building if you walk
towards flag 5. Along the side of this building, go to the window
on the right. Use a shotgun and run towards the window. Shoot at
it and you will find yourself under the flag 4 building.
Additionally in "The Nest" map in Conquest mode, stay up at flag
4. Take the stairs up and go through the hall to the right. You
will be at the cliff again, but go left and keep going until you
find a room with only a chair and table in it. Then, turn so you
run behind the chair. Run in between the wall and the chair and
lay down to be under another building.
