Good Protection In Desert On Multiplayer

This is good for Capture the Flag. If you are the first team (The one closest to the truck and demo kit point) the easiest thing to do while wait for your teamates to get the flag back, is to crouch down and get under the truck. It is best to be in between the wheels where you are even less likely to get hit. This will give you good protection from bullets and some protection from explosions. Also the truck cannot be destroyed. The reason why this works so well is that the computer players are too stupid to crawl up under the truck and shoot you. But your allies would probably take care of them anyway. But, if you get killed, you have to get your flag back quickly, you alliest are too stupid to crawl under the truck too, and after about 30 seconds, the flag returns to the enemy base.

Mission 12: Sniping Location

Note: This trick requires a Locktopus. To the right of the bridge are stairs. Go up until you reach the top. Then, go up to the ladder and pick the lock. This will give you a great sniping location, and you can bypass the enemies.

Easy Weapons

Once one player has gotten a weapon that another desires, go to Club:Stakeout on Agent. Drop that player's weapon to a second player. Have any one of those players continue through the level normally. If done correctly, the new player could have the weapons in less than three minutes. The faster way through the level is to run in the club after the first objective is complete unarmed, and rush to the very top to Jack Dark.

Dummy Flag

In a capture the flag game, have one player get the flag and bring it back to his base to score. Before he scores, have the party leader go to the enemy base and stand on the enemy flag holder (the colored circle under where the flag starts). Stand over it in a position so that he can see the color on every part inside of the circle. Once he is positioned, score the flag and stay there. Every time you score it should say "Enemy flag returned" at the bottom. After that, the flag will come back out as though you dropped it before you made it to the scoring spot. If you stand there, the flag will score very quickly, but you will not be able to tell until the round is over and it shows the scores. If the player on the enemy flag holder dies or moves too far away for any reason, the flag will come back to the enemy base.

Hawk's Barrier

Have a Hawk and one of the two vehicles. Throw the Hawk and get on the vehicle. While driving around, hold the RB and the secondary function of the Hawk will activate. Usually the Hawk's secondary function will protect you from explosions and have a white lined barrier appear around you. However this glitch will only provide the visual effect and will not protect you. This does not work on the gunner position of the hovercraft.

Plasma And Rocket Turret

If you have a plasma gun or rocket launcher, get on the gunner position on a hovercraft and press Y once to swap it with the M60. You will now have unlimited ammunition for whichever you choose to put on the hovercraft. This trick can also be used to get a free M60 on a level that does not normally have one.

Desert: See Through Wall

At the Desert multi-player map, there is an area where you can take cover and see through the wall. In order to do this, you must have Bases 2 and 4 open. Go into the cave temple base. Once you go through the hall, go up the sand hill, and not the stairs. Go in the little courtyard from either entrance then turn left. There should be a bowl near the wall. Stand as close to the wall and as far in as you can into the wedge created. While standing, go into cover. If done correctly, you should be able to see through the wall. This is most effective during the Infection game type with the Plasma Rifle. Hide there and whenever you see a skeleton, use the secondary function (invisibility). They will usually walk out because it is very difficult to see you.

Cover Mode

While in cover mode and standing, move the crosshairs up to the very top then over towards you. You will be able to see more of what is on the other side of the cover that you could not see before.
