Simply adds level appropriate, and/or craftable masks from the game Payday 2.

You can acquire the masks through the original author's loot box, (Near sanctuary) through crafting, or through the leveled list.

Levels are based on the radiation/burn/ballistic resistance you get from the mask. You get access to new masks at Level One, Level Twenty Five, and level Thirty. A few masks require ranks in "Armorer".

Be sure to report any issues that come up, as well as any different versions you'd like to see. If you'd like to see new masks added you can ask the original author linked above.
