T - This is just above the entrance to the parking garage area.

A - This is on one of the small container things that are on your lefthand side before getting to the warehouse with the Chryatis.

R - This is inside the warehouse on one of the catwalk things.

H - This is on the bottom inside the Akrid area. It will be to the right of the big hive thing (the thing that you are inside of when fighting the boss).

E - This is on a small ledge to the left before you reach the three hives for the Akrid. You can jump down to it if you want, I anchored off the ledge, descended, shot it, and went back up.
