Ballista

The ballista is a new weapon first occurring in Doom Eternal. It launches kinetic projectiles with results similar to those of a rail gun, and can be charged to fire an explosive bolt which tears apart enemies. It is currently presumed to replace the previous game's Gauss cannon given its similar mechanics.

One feature that is inherited from the gauss cannon is its Precision Bolt mod, the Ballista can be zoomed in to charge up a more powerful shot.
