Change Soldier color
You can change the color of your soldier from white to black or black to white by blowing him up with a grenade and finishing the level. Note: He will lose experience -- do this early.
Charge the Enemy
The game sends an infinite amount of troops after the alarm has been set. The best way to defend yourself is to charge ahead as fast, but also as safely, as possible. In some levels you can cut down the number of men by almost fifty. If you are low on ammunition, health, etc., this is a good way to cut down on the amount of men you have to deal with. It also works sometimes if you send a man far ahead and hold him there, then do your objectives for your mission.
Cheat Menu
When you are on the Main Menu screen, use the D-Pad and buttons X and Y to enter the following: Left, Left, Right, Right, Up, Up, Down, Down, X, X, Y, Y. When you enter this, go to the options menu and the Cheat Menu should be available. In the Cheat Menu, you can change the "Tropper Level", "Enemy AI", and the "Mission List".
Desert Watch: Go through mountain
This trick requires some practice. Go to the middle top of the hill. Look to the left. You will see a mountain that looks like you cannot. When you climb it, go to the hill and push up hard. When you get to the top of the edge, turn the Analog-stick Left (not too fast). When you do, go straight up and you will go through the mountain.
Destroying Heavy armor tanks
Find the man with C4s and give his detonator to someone else. Keep everyone back except for the man who has the C4. Quickly run to the tank and plant the C4. When you are finished, get another troop to call him back. When he runs back, the tank should be focused on him. Change to the man with the detonator and use it. If this works, everyone should make it out alive. However, if he does not make it, you can clear the area then heal him.
Easy kill on satellite tanks
To take out the tanks with the satellite dish on top, shoot the satellite dish with a sniper rifle and the tank will explode.
Easy stats
If you want Foley to calm himself faster in between shots with his sniper rifle, enable the "Cheat mode" code. Select a short and easy mission (such as Safe Passage, Special Delivery, etc.). It does not matter which team you choose (U.S. Delta Force or British SAS). Do these missions repeatedly about three times. Foley should get a level increase, be promoted a rank, get a Sniper skill star, and if your accuracy is high enough, a service medal. This trick only works if Foley gets over 65% accuracy on the missions.
Last resort attacks on tanks
If you need to take out a tank but have no more long range rockets, it is possible to get close to it without getting hit. First, you will need to have a sniper rifle to zoom in on the top of the tank to take out the gunner, if there is one. After he is down, throw a smoke bomb in the direction of the tank. Try to get the smoke bomb in as close to it as possible. While the smoke is in the air, you can run up to the tank without being hit. The smoke will make it impossible for the tank to see you. Get directly next to the tank and plant a C4 next to it. After it is planted, throw another smoke bomb slightly further away from the tank. Make a mad dash for the smoke. If you are fast enough, you will get behind the wall of smoke and can then make your way to safety. Then, detonate the C4.
Last resort on SCUDS
SCUDs can be blown up with the sniper rifle if they are in the launch position. Shoot the rocket a few times with it.
Secret Cameras
Have you noticed the few cameras hidden throughout the game? In Conflict: Desert Storm there are hidden cameras around random levels in the game. These might occur when you expierience slowdowns, as they are recording your/your teammates every move. One huge giveaway is in one level, the one you pick up Emir and Conners, you spot the red News Helicopter (I tried to shoot the cameraman out of the door with Foley). The footage being taped gets released at the end of the game when you finish the last mission.
Spreading out Amunitions
Do not give too much of the powerful items such as tank mines, C4, anti-tank guns, etc. to a single person. If you have this person advance and he gets taken down by a tank, your other teammates might not have the firepower needed to even get close to the downed person, let alone heal him. It is always a good idea to have each teammate equipped with at the least one high powered explosive in case you need to take something out.
