B - This is on the ledge above the door that is just behind you at the very start of this level.

I - This is in the small rock formation just before you drop into the second tunnel thing.

R - This is by the light on the ledge across from where you come into the large city area. It is pretty much above where the crack in the wall is where the two Wasps were.

D - This is on a small ledge to the southwest of the VS in the room just before the mini boss.

Z - This is under the VS at the start of the second area down the left hand hallway. Move the VS to see it, or go to the side and snipe it.

L - This is on the ledge to the side of the storage unit on the southern end of the second area. It will be up on the upper ledge.

Z - This is just above the storage unit that the L was located next to, on top of some piping above.

A - This is in the room with all the VS's. It is by the large stack of crates underneath it in one of the small red fenced things on the western side of the crates.
