The Arc Cannon is an anti-air weapon unique to the Helghast. It uses Petrusite as its primary ammo and fires an electrical beam into the air to combat air units. It uses the chassis of a Helghast tracked APC and has a large primary cannon on top. It is likely weaker than the normal APC as it has no anti-infantry or ant-tank armament and must be protected by stronger units. The arc cannon is highly mobile and most likely cannot engage ISA cruisers as effectively as their larger brethren, though they still are useful against intruders.[[Category:Technology]
