Ghost Recon

When playing in multi-player mode, find the large building with a Russian flag flying in front of it. Go through the gate and take a right, then a left, then another left, then turn around. There will be a stairway. Go up it into the building and go up those stairs. Take the first left and you will find a very nice sniping location.

Purple Heart: Get wounded or killed in action.
Bronze Star: Get 15 kills
Silver Star: Get 20 kills
Distinguished Service Cross: Get 25 kills
Congressional Medal Of Honor: Get 30 kills

In multi-player mode, choose a rifleman and get Kit 6 (MP5 SD, extra ammunition). This kit will almost win every battle because it has a 30 shot clip and you can walk while looking in the scope. You will have great accuracy with most of the shots. It really does not matter what gun your opponent chooses, unless they select the same kit. The M136 and other powerful weapons take a long time to aim.

If you are a sniper looking for your enemy when he is hiding in the trees, zoom in with your sniper gun. Look around the trees until the crosshairs turn red. When this happens, you can be almost sure that the enemy is there. You can either shoot him or take out your pistol to save yourself some ammo for your sniper gun, since you are already in position.

When playing in multi-player mode on the city Gold Mt. Level, there is a nice hidden sniping location. In the mission there was a shot down helicopter. To the west will be a strip of the road going down. Go straight ahead. On the front left side is a door. Enter it and go up the stairs to the end of the building. You should be looking out a third story window.

When you meet up with the allied tank go forward. The first building on the left will have several soldiers in it. One man has an anti-tank rocket. Eliminate him as soon has possible to stop him from destroying the allied tank.

Press Back, then press Back, A(2), B, X, Back during game play. A message will confirm correct code entry. Your first soldier will be invincible, but the remaining members of your platoon can still be harmed. Note: You cannot complete the game normally when this code is active, as maps and dossier items can no longer be unlocked.

Note: If you switch to the last character on Alpha, then enable the "Invincibility (self)" code, the entire team, including Bravo, will have invincibility.
