O - This is between the two storage units near the start of the level. The two units are to the West on the map.

A - This is near the end of the first area. It will be in the corner of the last hallway just before the end of the first area.

T - This is up north by the warehouse place, it will be on a ledge on the east side just before the truck with the two VS's on it.

N - This is on a ledge of the junked warehouse on the southern edge of it, look upwards on the toward on of the upper ledges of the warehouses' frame.

D - This is at the far north wall inside the right tower at the top.

O - This is under the flooring of the stairs that lead down after the top level. Drop down to the level just below the top at the beginning of this area and look at the flooring under the beginning of the stairs at the top.

R - This is in the middle of the wall on the south side of the last area. A bit hard to find if you don't know where to look. I went all the way across and to the top side on the area across from the start and looked behind me to see it hovering on the wall.
