E - Right at the start, head to your right a little bit and look up, easy to spot.

O - A bit easy to, as you head down the first walkway killing all the Akrid and the hives, you will see one that has a rock directly over it. It is the one just before where the hole is to drop into the room below. Look up and to the right to see the mark on a small ledge.

R - In the room with all the Nevec soldiers. There will be the two platforms on your right. One lower, one higher, its at the edge where those two connect jammed in a small space, you will see it if you get close enough.

M - This is a tricky one, when you get to the part where you ride the platform you will see the fire start, it is just past the fire on the inside in the middle of the rail, you will have to zoom in and be quick to get it.

E - While anchoring your way to the top, you will come to a ledge that has two of the T-ENG containers on it, go to the right side of that, drop off the ledge so that you anchor on before falling, anchor down a little bit and it is just under the ledge of that platform.

T - This isn't too bad to find, once you come out of the building anchoring your way up, it is just to the left, it will be on the wall, head as far to the left as you can where the ledge ends and just look closely and you will see it.
