Rainbow Six 3: Raven Shield Cheats

Oil refinery:
On the first level that you are in an oil refinery, take an HE grenade launcher as your secondary weapon. At the end when the enemies fire RPGs, take it out. Step out from under the roof area so that enemy fires an RPG. Three enemies will appear. Shoot an HE round to kill them. Move back under the roof, reload you HE Grenade launcher, and wait until a second RPG is fired. Move around the corner and with your HE grenade launcher and shoot the man that is standing there. Turn around, and when the garage door opens, shoot the barrels on the right side with your primary weapon. Kill all enemies, secure the hostage, and the level will be completed. REMEMBER: It recommended that you save the game when you open the door that leads to the RPG area.

How to conserve ammunition:
After every fire fight, reload even if you have 22 rounds remaining. If you keep doing this, you should have enough ammunition for the long fire fights and levels.

Press Reload (X by default) before you use a full clip, you will not lose that clip. You will get a free full clip.
