Walkthrough
This level is fairly easy to complete solo. It is exactly the same as 'The Pit' in S.S.D.D. If you can complete this level with 3 stars then you should be able to get the Pit Boss achievement. the difference is that in SSDD(campaign) there is the bonus/malus system, bonus for precision and malus for killing civilian and forgetting targets. in the pit(co-op), only time counts and you have tou come back if forgetting a target, and you just fail if killing too civilian(no malus if killing a few)

You can use either the machine gun or your USP Pistol, however the pistol is better for taking out individual targets. It may be best to use a combination of the two, depending on how you handle the weapons. For example, after completing position 5, switching to the USP can help reduce the chance of hitting a civilian. the M9 pistol, having the best walking speed when firing, is indeed best in SSDD(campaign), when precision counts. in co-op, using full auto is possible as precision does not count. still, killing civilian is more likely if you spray bullets all over the place.

Complete the course by following the information provided for each position, below.

Position 1
Shoot the first three targets then continue on to position two.

Position 2
There will be a civilian in front of one enemy and one enemy to the right. Wait for the enemy to move, then shoot both targets and continue.

Position 3
Shoot the enemy target in front of you, then look upstairs. Take out the enemy on the right first then the one on the left. Finally take out the target in the middle window. As you're running towards the final target at the door, reload, then knife the target to the left.

Position 4
There are two enemies to the right and one straight in front of the door. Go forward and get the one in front of the door, then turn right and get the other two. Reload again, go up the stairs and knife the target.

Position 5
There are four targets and two civilians, so shoot all four enemies, (you can align both shots, so one shot takes down two of them). Then reload and go down to the next and hardest area.

Position 6
Shoot the one enemy target to the right, then get to the right of the car. When you are there, you can shoot two enemy targets at the same time. There is one final one to the very left then continue.

Position 7
Shoot the two final targets then sprint to the finish.
