The Medic class units are the medics of Specter Team with the special ability of draining life from enemies by using the XR-42 Phoenix, as an iconic default weapon, and impart it to the other injured teammates.
During the berserk, the Phoenix's beam paralyze any enemy it touches. While paralyzed, enemies take damage over time and cannot move from where they are. This damage is converted to energy in the Phoenix.
When the berserk is attained, the medic may revive himself when next incapacitated. If this berserk is not used when incapacitated and the medic is not revived by someone else, the berserk will be lost.
