Dirty Bomb Maps w/ Spawns, Ammo, Secondary Obj., MG Nest

This is intended to be a guide for those new to Dirty Bomb to learn places of interest in the maps that are not necessarily indicated in game, or aren't very well highlighted in game. Click each image for a larger version. If I've missed something, apologies, and please let me know in the comments, I'll fix it/add it in when I get a chance.

June 18 edit:All 5 maps should be updated to reflect today's changes. I'll be refining it constantly as new things get found or are missing, if I miss something, let me know in the comments, I'll look into it and fix as necessary.

Used map from ingame that is more accurate.
Note: One of the MG nests is only available after building the secondary objective associated with it.

I attempted to split the upper and lower halves, as the level folds upon itself. The main Image is the upper level up to the second elevator, and the lower level with the final Defender spawn and final plant. The inserted lower level is from the second elevator (bottom level) and indicates the two secondary objectives and ammo crate.
