At the beginning of this mission you see Mark's wife, Susie, and his son, Alex, walking after coming out of their home. Unfortunately, Susie gets killed and Alex is kidnapped while Mark is lying on his bed home nearby. Mark runs outside to see what's happened and finds his wife on the ground, dead. His son is put in a car and they drive away. Now you have to follow them to their hideout. Right when you can play follow the red car as fast as you can. If you lose it, don't worry, just follow these directions:

From as soon as you take control:

Turn right

Go through the small intersection

Turn left

Continue over the pavement at the next intersection

Sharp right

Sharp right

Turn left

Cross the bridge

Stay left at the roundabout and take the first road on the left

Drive on the center line between the two lanes to get past traffic

Go through the next intersection

Continue past a road that comes from the left

Go through the next intersection

Past another left

Take the NEXT left

Another left

Get out by the red car and walk into the open area through the door by the car. Pull out your gun and auto-aim at the guard beside the trailer and the guard behind the trailer, killing them both. Then free-aim at the gas barrels up high near the entrance of the warehouse; there is a guy behind them. After it explodes the stairs will fall down over there and he will die. Soon, a guard with a pistol comes out. Sometimes another guard with an AK-47 comes out of the doorway soon after the first guy, if they do kill them both and run up to the AK-47 that the recently exploded guard dropped. If you've taken many hits, don't go into the warehouse yet. Instead heal against the closest wall. Now walk into the warehouse and duck behind the blue crate which is in front of you and to the right a bit.

When you're ducking behind the blue crate, you should see 2 guards, one behind some boxes, the other near some more. Peek around the crate on the left and kill the guard by the closest to you and the guard behind the crate will duck. Use this time to walk up to the crate and wait for him to get up. When he does, kill him. Wait awhile, heal yourself if you want, and a guard with a Shotgun will come, kill him. Go against the left boxes (The huge stack) and make it so you can see a guard come closer to you, kill him by coming around the corner and go off the wall. Go back towards the entrance and go right and go against the boxes so you can see around the corner. There will be a guard on the stairs pretty far away. Shoot around the corner (without moving) until another guard walks right into your bullets and dies. Then kill the guard on the stairs by peeking around the corner. Walk around the corner and activates a guard to come out of the left room, kill him. If you want a Shotgun, enter the room where the guard on the stairs was. If not, go towards the right side of the back wall and go through the doorway to enter the main section of the warehouse. Don't worry about the area where you first were; there's nothing else interesting. But if you need to heal, do it before you continue.

In this area, quickly run over to the right side of the crate in front of you. A guard wil walk by, so quicky auto-aim at him and kill him before he gets behind the crates. If you don't cap him, just run around the corner while auto-aiming and you should target him, and kill him. After going right around that corner, put your back against the tall boxes. Jump out around the corner, auto-aim and blast the guard standing there (Don't try to poke your gun out and shoot him because the bullets won't hit him. They miss horribly). Go around the nest left corner. A guard will pop out, quickly blast him before he gets a shot off. All that noise attracts another guard approximatley 90 degrees to your right. Take him out then heal before going up the stairs which are where the 2nd last guy you killed came from.

When you walk through the doorway, you hear some 2 guards talking. Go up the first few steps to the platform on the stairs, and take out the poor sucker at the top looking in another direction. Now continue up the stairs and put your back against the wall on the left side of the doorway. You can see 2 guards coming, jump out and blast them as fast as you can, then run to their corpses and another guard approaches. Quickly blast him too. You could also shoot the explosive barrels if the guards are near them if you would like. Continue by following the hallway until you come to a corner. Once again put your back to the wall and you should see a guard patrolling the next hallway. Jump out and cap him when you get a chance then you should see another guard through the doorway behind the guard you just killed. Blast him, go to his corpse and you should see another guard run by. It appears that he ran into the room to the left. Follow him for a video, to beat the mission.
