Full body female character concept. The body suit is designed to be circulatory with the metal headpiece/backpack. 

The mask filters to remove hazardous element and provide supplementary oxygen derived from the body suit (picking up perspiration). The outer part of the backpack is for water collection (drinkable), which is harvested through both the air filtration and body suit.

SMG weapon concept. The gun will feature several upgrades such as a buttstock, foldable buttstock, and two scope level upgrades (the smaller scope as shown and a red-dot scope).
