Target Marks: Mission 6 | Target Marks Lost Planet Guide

Behind some rocks at the beginning of the level.

When you turn left into the Nevec-controlled street, it's to the left, near one of the missile turrets.

Under the second bridge, right side of the street.

At the top of one of the building at the end of the street.

Just before the cut-scene, in a tunnel between the street and the dome approach.

On the right side of the tunnel where you are after the cut-scene.

In the last room before the boss fight.
