Fusion Cannon

Fires destructive blasts of energy directly from the ship’s fusion reactor. ---Descent Manual description

The Fusion Cannon is the fifth primary weapon in Descent and Descent II. There are several mechanics in the way this weapon works. The cannon fires two beams with size and power that varies based on how long the fire button is held down. The more powerful the beams, the more energy from the ship's core is used. If the fire button is held for too long, the shields will be drained. The cannon can be unwieldly and difficult to aim while charging due to the recoil, making it better suited for tackling robots up close.
