This drone fires a laser that goes through multiple targets, causing a good amount of damage to them. This drone is notably more expensive than normal, assault, healing and even missile drones while also being around the same price as Flame drones.
Note that its re-fire rate also makes it the slowest firing drone in the game, thus not having great damage output. Its ability to damage large groups via its penetrating attack, however, easily covers its low rate of fire.
This drone won't benefit greatly from Arms Race, as it fires very scarcely.
