Bronze Log: While still outside, on the first platform with all the red lasers (where Carla explains what they are to you) you can drop to the lower one (heading 230°). From there go to the right of the large central pillar to find one of the round rolling robots that gives this log. (there is another of the same robot on the other side of the pillar that doesn’t give a log).
Bronze Log: From the previous enemy fly up to the next platform immediately above (heading 350°). Go around the large pillar on this platform for another one of the same round robots.
Silver Log: On the next large open platform (train turntable in the middle, Brute starts talking to you over the radio) there is a yellow tetrapod MT that gives this Silver Log.
Bronze Log: When progressing towards the main objective marker, an enemy in your way will start putting up a green bubble shield. Go inside the green bubble shield and defeat the round robot deploying the shield for this log.
Platinum Log: Automatic from defeating the main story objective “Honest Brute”. He’s the main boss at the end of this mission, can’t miss him.
