Static cannon

The static cannon (also known as the static rifle) is a multiplayer weapon that appears in the Doom game. Powered by static electricity, the static cannon is a slow-firing beam rifle which, rather than using typical ammunition, has batteries which are charged by the player's motion - the player must sprint to increase the weapon's charge level. When standing still, the weapon's charge will slowly drain. It has been compared by PC Gamer journalists to a no-scope sniper rifle requiring on-the-move accuracy. Its modified firing mode allows a zoomed in view for long-range sniping.
