To counter the superior air power of the Brotherhood and massive infantry power of the Minutemen, the Institute has developed a new weapon, the Anti Air/Anti Infantry Plasma Cannon. This new technology uses a near instantaneous plasma beam that at the point of contact builds plasma energy and releases it in an outward explosion. Perfect for ripping through airborne Vertibirds, immobalizing power armor, or decimating infantry formations. A fusion core was chosen to power the weapon because of its vast energy supply, able to keep structures power running for centuries. If this deadly new technology were to fall into the hands of the Institutes enemies, the results would be catastrophic.

Version 1.80 should be the final version as all issues are resolved. Any future updates should be optional files.
