Reactive XT800

Overview
"Created by the same group who pioneered the Reactive SLX and the Exterminator GT, the Reactive XT800 armour was rumored to be the most durable armour ever known to man upon its creation. A widely-circulated pre-outbreak video shows a prototype taking five seconds of continuous GAU-8 fire, and still looking brand new after the test. Very little is known about this armour, thanks to the usual government classifications and the developers being tight-lipped about the project. Even if you are lucky enough to find one, keep in mind such a complex piece of armour can only be repaired by the most experienced and knowledgeable engineers."
