Completing the Chameleon Challenge
For the chameleon challenge you are required to pick up the Factory Guard, the Patriot and the Patriot’s Entourage outfit.
Load into the Patriot’s Hangar on the normal difficulty. Sneak around the outside of the hangar over the stacked wooden crates. Pick up the hammer on the other side. Go across the Hangar and go to the gasoline can. When you are there throw the hammer at the barrels ahead and pick up the gasoline can. Make your way through the stacked crates to pick up the Factory Guard outfit that is on a barrel ahead. Go to the back of the Patriot’s bus and sabotage the generator. Take out the guy that comes to investigate when he is near the front of the bus and drag him behind the row of crates nearby. Take his outfit and steal the teddy. Go to where you exited the area with the stacked up crates and wait for a guard to show up. Garrote him and hide the body in a crate nearby. Then also hide the guy that you garroted earlier. Now you have to wait for the Patriot to realize that the teddy is gone. Once his entourage has left throw the gasoline can on the floor to the right and garrote the Patriot when he comes to investigate. Drag the body fully behind the crates, then take the Patriot’s outfit.

Make your way all the way back to the starting area the same way you got to the key card. Open the backstage entrance, go down into the elevator shaft and into the air ventilation shaft. Go to the exit. In the Arena make your way to the other side of the area and through the bar to the top. Go into the room overlooking fight and enter point shoot mode to take out all the enemies in that room. Keep going up and take out both the guards in the catwalk above. Release the lighting and go the other way down to the bottom level. Before you go through the bar take cover on the boxes so that you are out of sight of the bar and wait for tha bartender to walk past. Then go out into the main area and exit the Arena.

Completing the Light Rig Challenge
For the Light Rig challenge you are required to kill Sanchez by dropping the lighting onto him.
Continue on from Lost and Found. Go to near the guard in the back of the Hangar and pick up the gasoline can nearby. Throw it at the barrels in the corner of the Hangar and pick up the factory guard outfit on the barrel near where the guard stood. Then go back to the starting area the same way you got there. Go into the backstage entrance and through the air ventilation shaft to exit the Patriot’s Hangar. In the Arena go around the fenced off area to the second bar. Go through the bar to go up the stairs and then go into the room overlooking the Arena. Use instinct to get past the guard standing in it. Keep going up through the door ahead using the key card. When you get to the catwalk go to the middle area and take cover on the right side of the doorway ahead. Wait for the guard to go past you, then garrote him. Now you can release the lighting.
Completing the Wingman Challenge
For the Wingman challenge you are required to help the Patriot win by sniping Sanchez just after the Patriot has hit Sanchez.
Continue on from the Light Rig challenge by reloading from checkpoint. Go through the same bar as in the Light Rig challenge. At the top of the stairs turn right and go down the stairs ahead. Go into the area ahead through the locked door using the key card. Garrote the guard standing in the room and leave the body on the ground. Shoot the guard sitting on the sofa in the other room. Take the sniper rifle and go out through the other door and down the catwalk ahead using instinct as required. At the end of the catwalk turn left and right and go through the locked door ahead. Go up to the top and look out through the window with the scope of the sniper rifle. Wait for the Patriot to hit Sanchez, then shoot Sanchez in the lower belly to avoid shooting civilians. Then hide on the half wall and wait for the guards to leave.

The My Enemy challenge requires you to kill Sanchez using explosives.
Continue on from the Wingman challenge by reloading from checkpoint. Go up to the upper level in the same way as before and go to the locked off area.
