Soldier Of Fortune

Hint: Using the reticle:
When fighting enemies, pay attention to the reticle. If it sights red, you can shoot safely. However, if it sights green or white, it indicates a hostage or a person that is on your side. Do not shoot; pass them and leave them alone. Some enemies can kill hostages if you are not careful. Do not worry about that, as you cannot save them all.

Hint: Using the nightvision goggles:
You cannot shoot enemies in the dark. It is impossible to see them. Use your nightvision goggles to light up any enemies in your area. You can still use weapons. However, remember that the nightvison goggles have to be charged, or wait awhile before they charge up.

Hint: Training:
If you are a beginner, play the training level to get tips. This will help when you go into the real missions. They are no guards with guns, and you can only shoot pictures of enemies.

Hint: Saving ammunition:
Use your knife to collect more ammunition for the other guns. By doing this, you can get full ammunition for every gun you have. If you are using a flamethrower in the later levels, use a short burst to conserve fuel. Use the magnum when low on gas canisters for the flamethrower. The rocket launcher packs serious damage. Use the primary fire button to fire a single shot. Shooting multiple times is a waste of rockets. You can use this gun on single armored foes or groups of enemies.

Hint: Tanks:
Assault transports such as tanks will not actually harm you during any mission that features them. They do not target you with their machine guns. Do not waste sub machine gun rounds on them. Its better to leave them alone.

Hint: Enemies with flamethrowers:
Watch out for enemies with flamethrowers. They cause massive damage to your armor. Shoot them with a heavy machine gun or a .44 Magnum. Watch the gray bar. Basically, your armor will deplete before the health bar starts to shrink when you are hit by enemies.

Hint: Defeating Sergei Dekker:
Before you encounter Sergei, collect everything, especially if you are low on heavy machine gun ammunition. Get ready for a massive fight. Shoot the enemies with the heavy machine gun. Once you killed them all, Dekker will appear. Use your heavy gun on him to kill him quicker. Ammunition boxes will appear and become collectable.

When you enter the room, get all the heavy machine gun ammunition. Once you kill all of his guards, restock the heavy machine gun ammunition. Go directly next to him and just shoot him nonstop. Do not let him enter the room he first entered from. If he does, you will be killed by the machine guns in the corners and on the submarine. Also try to aim for his neck. It seems to drain his health more quickly.
