This is a medium damage turret with unlimited range and can damage multiple enemies in a line. For high damage more than one turret is required. Laser Turrets have slow firerate so a fast-firing counter-part is required, especially on wide spread maps where the bugs are everywhere. They also turn fast, unlike Sniper Turrets. If you've got more than one Laser Turret, then never buy a Scouter Turret, even if the fourth turret is a Magnifier. You are wasting your money by buying something that will have no effect on the Laser Turret. They're useful on maps like Kitchen, Office, Pond or Living Room. Costs 500$ to build, and it's not very cheap to upgrade.
