Photon cannon

The photon cannon is a Scrin heavy anti-armour base defense, rivalling GDI Guardian cannons and Nod laser turrets. Despite their name, they appear to use plasma discs as a main weapon. They can be upgraded with Tiberium shard launchers, increasing their damage per second output by nearly 140%. 
They cannot target aircraft, relying on Plasma Missile Batteries for that purpose. They are often paired with Buzzer Hives as well, to cover their weakness to infantry.
