1. At the start of the level go to the right. Go into the area with the pillars and scaffolding and look at the slightly raised area against the wall ahead of you to find the sensor.
2. Back to the starting position, go left this time and almost immediately to your left will be a sensor on the ground in a semi enclosed area with three pillars.
EMBLEM 1 - Follow the passage around to where you'll see a factory building with two smokestacks ahead of you. Move to the front of this building and turn left to find the emblem on the ground.
3. Jump up to the roof of the building next to the factory building and look back towards the starting point. Jump up and hover to find the sensor on the roof of the building across from you.
4. Go to the way-point and turn left. You'll see the sensor on one of the ledges behind the pillars.
5. Right next to #4 is a side passage lined with cargo containers, jump up to this passage and follow it around to the right. The sensor will be on the ground on the right side across from a small area with ammo and repair pick-ups.
6. Follow the passage around and return to the main road. When you are about to pass under an orange banner turn to the right and look at the "Meat Market" building. A sensor will be above the attached garage on the left side of the building.
7. After the circular area, go out the gate and jump up on the platform ahead. The sensor will be between the spherical tanks to your left.
8. If you move ahead from your current position you'll see a large area with several stacks of cargo containers. You'll see a sensor on a platform against the left side. If you'd entered the area from the gate, it would be on the platform immediately to your left as you enter.
EMBLEM 2 - From #8, you'll see the platform forms an L shape, the building ending just before you reach the way-point Go to the end of the building and turn left, going around the stacked containers at the end. You'll find the emblem in a small alcove between the containers and the wall. If you hit the way-point you've gone too far.
*** GET EMBLEM 3 AND SENSOR 9 BEFORE ELIMINATING THE ENEMIES ***
EMBLEM 3 - When you enter the next area, you'll get the objective "Eliminate enemy forces defending the entrance". Immediately go all the way to the left, and you'll see the emblem between two pillars above you.
9. This time go all the way to the right, and you'll find the sensor in a similar position, between two pillars above you.
*** GET SENSOR 10 BEFORE DEFEATING ENEMY UNITS IN THE WAREHOUSE ***
10. From your starting position, you'll find the sensor at the back of the area on the left side.
11. On foot, before you move turn left. The first sensor is against the left wall near the corner.
KEY 1 - Between the two computer consoles closest to the ramp.
SCRAMBLER 1 - On one of the two computer consoles further away from the ramp.
SCRAMBLER 2 - On the wall just to the left of the ramp entrance. At about the same height as the hanging light.
SCRAMBLER 3 - At the top of the ramp is a console that you hide behind for the fire-fight. On this console is the scrambler.
12. After the first fire-fight, when you enter the room with the map table, turn around towards the ramp you entered by and look up at the ceiling. A sensor will be on the ceiling between two screens.
KEY 2 - On one of the consoles in the room.
13. when you leave the room and move towards the way-point, you'll practically trip over it at the bottom of the ramp.
SCRAMBLER 4 - In the next room after the second fire-fight, stand at the top of the entrance ramp and look past the three stacked boxes with green trim. To the right of the boxes you'll see a door, and to the right of that the scrambler.
SCRAMBLER 5 - In this same room, near the ramp somewhere. I destroyed it accidentally with an explosion, so I'm not certain of its exact position.
14. In the pit under the hydraulic lift that the ballistic soldier was standing on.
KEY 3 - On a stack of boxes in this room.
15. stand at the top of the second ramp leading out of this room and look left to the left. You'll see a sensor behind the crate on the small platform nearby.
16. Keep turning to your left and you'll see another one on the catwalk above the entrance ramp.
KEY 4 - Leaving the area of the second fire-fight, you'll enter a large open area. Go along the walkway and down the ramp, then continue straight to the edge of the platform. The key will be on a stack of boxes to the left.
17. Standing right where you get Key 4 with your left side pressed against the green and white boxes, looking out at the desert. There will be two rock towers ahead of you, the sensor is near the base of the one on the right. You'll just barely be able to hit it with precision aim over the edge of the railing.
18. In the same position as you were for #17, look to the right on the other side of the right rock tower. You'll see the sensor on the desert floor between some grass and the tower's shadow.
SCRAMBLER 6 - In the center of the area is a large steel container. Stand next to it and look towards the door you entered. You'll see the scrambler on the side of the walkway railing.
KEY 5 - Go up the other ramp, but don't enter the doorway. Instead go to the end of the walkway to find the key on the ground.
*** GET THE LAST TWO SENSORS AND SCRAMBLER 7 BEFORE KILLING ALL THE ENEMIES IN THE ROOM ***
19. Enter the doorway and just past the boxes turn right and look down. The sensor will be on the ground behind the hydraulic lift.
SCRAMBLER 7 - In the pit beneath the hydraulic lift in this room.
20. Standing across from the hydraulic lift, look back towards the walkway you entered on, and look down below it on the ground to find the sensor.
