Difficulty levels change the enemy soldiers' abilities.
Your mission is to rescue two groups of hostages that are being kept on the platforms.
In front of you there's the first room. Once you breach it, take out the enemies inside #1. After a while the gate will open and you will be able to move on. Stand in a convenient position #2, from which you will be able to easily eliminate the incoming enemies.
Go straight. Once you get up, use the grenade launcher to destroy the containers in the distance #1. You will eliminate a couple of enemies this way. Once you're around the middle, a chopper will show up. Try to eliminate it as fast as you can #2 by using the grenade launcher. There's a rocket launcher on the ground, but you'll do it faster with your primary weapon.
Move on. Before you get to the stairs, some more enemies will appear. On the highest difficulty setting you will have to deal with them in the smoke coming out of the smoke grenades they throw #1. You will find a weapon with a thermal vision sight by the container. Move to the right. Your first task is to eliminate the enemies in the windows on the upper floor #2. Look out - they're equipped with rocket launchers.
Once you get the spot where the hostages are being held #1, change your weapon - don't breach in with a thermal vision no matter what. Inside you have to deal with some enemies #2 - take them out during the bullet time.
