Mobile Arc Towers and Arc Batteries are the Helghast's secret defenses of Pyrrhus and are introduced during the Blood Meridian section of Killzone 2. They are powered by the unique and powerful element only found on Helghan, petrusite. They create large arcs of electricity, and anything that comes in contact with the arc is destroyed.
Usage of Arc Towers Edit
The Helghast were inspired to design Arc Towers by the hostile environment of their planet, although they draw the electricity for their operation from the Petrusite grid beneath Pyrrhus. The main use of the Towers has been to shoot down ISA aircraft (such as Intruders).
Once the electrical current has been charged inside the Arc Tower, it opens up its 'skin' to reveal the electrical rods that conduct the lightning. When firing, it releases a blast of dangerous electrical currents (called arcs) that can be devastating to ISA forces. The electricity is generated through an element called petrusite which is only found on the planet Helghan.
