Now drop most of your weapons (hang on to a pistol or the wire). Use the Rifle Target Practice Area to get the hang of rifles including the sniper rifle. Call the elevator with the button, then head to Basement 2. Simply walk slowly through it and shoot the red targets as they appear - at the end of this section a score will be displayed for you.
After the range, you will enter a 'maze'. In the next area you get to use sub-machineguns. Continue on to the Pistol Shooting Range and practice shooting with the pistols. Go through the door marked Close Combat Training Ground, and practice using the wire and knives on the dummy. Climb down the ladder and drop to the recess, then climb up the ladder and exit through the door. Follow the catwalk around and automatically jump to the next section. Walk straight ahead to climb over the rail, then climb the nearby ladder.
Go through the first door and change clothes.
