Equip the G-17 and fire one round into the wall in front of u. Then put your FAMAS into the box, the walk down the stairs then walk back up them, open the box and take the gun thats in there.

When you begin the second mission, you'll have a short time to kill all three enemies carrying viral containers. Two are in the sewer tunnels filled with water (and are found somewhat easily,) and one is in the large room with open pipes that continuously spawn enemies. After you kill all three viral container carriers, the clock will stop. To reach the viral container in the large room, you'll need to cross a pipe hand- over-hand. This leaves you open to the constantly spawning enemies from the pipes. To close the pipes, exit the large room by climbing the ladder on the wall adjacent to the platform where the viral container lies. Along the wall straight in front of you (or to the left as you head towards the end of the tunnel,) you'll find a room with generators and lots of enemies. Head up the steps in that room, and turn right in to the control room. There is a switch that you can hit (by pressing Triangle) that will close the pipes in the large sewer room. Head back, and you can collect the viral container without any trouble.

This hint is for those of you trying to get a good Marksmenship pecentage. Equip a good sniper rifle (The ACR Is My Perfered) and enter a mission. When an enemy comes on your radar, Press the auto target Button, then quickly press the manual aim button. If done correctly, you will automatically have the enemy in your sights. This makes for some easy Sniping.
This is a hint for all you non-sniper types out there, for the 2nd Cathridge level. Unlock the Air pistol first. Then all you have to do is run into the building, wait at the bottom of the stairs, and auto target the ALA Guys as they run down the steps. This should dispose of them with one shot.
When you go to kill the boss (whoever has the sniper rifle at the end of the level) go to the stairs you go up before you enter the room he is in. Then go straight across where he is shooting from. When you get past him there should be a gunman standing by a door to the left. Kill him and then turn to the right. You should see a room. Enter it. There should be a gunman inside, kill him and when you do that turn to the left wall. You should see a vent opening at the bottom crawl through. As you crawl along you will come to a spot where you can turn or go straight. Turn and after crawling for a while you will find a room with a box in it. It has the M16k in it. Get it and then climb back up the shaft. When you come to the spot where you turned take a left and you should come to where the boss is shooting from. Stay in the tunnel and wait for him to cross your path. He will not see you so don't worry. When you have a clear shot kill him.
