Ballistic armor

Ballistic Armor is the modern form of body armor in the 2050's, and one of the wearable items in Deus Ex.

Ballistic Armor uses electrically sensitive polymer sheets that activate upon impact from a bullet or other projectile. This absorbs the impact and protects the user from most of the damage. These suits are charged, and during use the plates lose their power and become useless. Ballistic Armor uses the Environmental Training skill; at Untrained the suit will remain charged for several seconds. At Trained level, they will remain charged 50% longer than usual. At Advanced, they will last twice as long as usual, and at Master level, they last 4 times as long as usual.
