We landed on Planet17X and discovered a new race of alien warriors, the Skayth. Negotiations for peace were short lived...The Leader of the legion let forth a blast of plasma from within his very arm! The results were devastating...our soldiers were completely annihilated. The species appears to have the ability to generate plasma like a spider creates silk. This biological matter is then electrically charged as it emits from the arm chamber. The largest Centurion versions have the ability to shoot in a continuous stream whereas the grunts shoot in charged blasts or pulse attacks.
