By 2499, Confederate scientists had developed a short-lived defensive matrix that could be created by science vessels. The technology gained a favorable reputation during the Brood War, where matrix technology was credited for saving many lives.
The battlecruiser produces a shield which absorbs 200 damage. The ability is not smartcast.
The defensive matrix is a temporary deflection field that helped save countless assets from a premature death during the original Brood War. Now the minds at LarsCorp have adapted this technolgoical marvel to protect the massive hull of the Minotaur-class battlecruiser.
