Pagoda: Get On Top Of The Main Bridge
To get on top of the main bridge at the start of the map, lay down directly under the edge of the bridge. Roll up towards the hill while looking at the water. You will start to see yourself flicker on top of the bridge. After a few times, you will be able to stand up and walk around. The only way to get down is to lay down and crawl backwards. You will fall to the bottom with no health damage. This works on squad matches.
Pagoda: Lay Down Under Water
Follow the directions to perform the 'Pagoda: Get on top of the main bridge' glitch. Once on top of the bridge, look down and line yourself up with the river. Turn around and lay down, then crawl backwards off the bridge. If done correctly, you should land in the middle of the river, still laying down. You will have a clear view of the valley in front of the bridge, and be able to shoot at anyone, but nobody will be able to see you. Be careful when using a grenade launcher. The grenade will detonate on the surface of the water at times.
Refill ammunition
Select the "Enter Cheats" option at the main menu, then press B(2), X(2).
Sniper Zoom On Any Weapon
Start a two through four player mission. Immediately kill one of your friends when you start. The killed player can now cycle through the other players' screens, and can zoom as if the gun where a sniper rifle. Have whoever wants to use the dead person's screen use it. The dead player can control the zoom, while the other player moves the character. This is extremely useful if the person that operates in the dead player's screen has a heavy machine gun.
Tree Top View in Lost Convoy
In lost convoy multiplayer mode for Xbox live, you can climb up onto a tree branch in sector C3. Approach the tree slowly while looking up at the branch (there is only one tree in that sector) and you will pop up onto the branch. From here you can snipe players trying to get into the swamp.
