Arklight - Acting Chaplain of the Viper Company Marines. This mountain of a man underwent extensive bio-skeletal reconstruction after a firefight in the Middle East which actually resulted in his death. Now more machine than man, Arklight's sanity has started to slip with memories of death of pain seeping in.

Joshua - The holographic construct that guards the Area51 operations core. Embodied with the personality of an unhinged but brilliant computer programmer, the construct hunts down its enemies and destroys them with electro-static based attacks; damaging the power sources that power this construct is the only hope of its defeat

Stinger - Stinger is a search and destroy craft, it is the punch that backs up the viper company's paratrooper corps. Its gyro-stabiliser is adapted for extra tight turning and it's fully reinforced with non-terrestrial (i.e. Alien) based alloys. Couple that with its water cooled chain gun and nano-replicating sidewinder rockets and Stinger becomes a most deadly opponent.

Z208 - Area51's first fully independent automaton, which was designed, has a mobile, battlefield support unit. It contains many forms of antiaircraft and antiballistic missile technology as well as a composite exotic alloy shell making it reflective to conventional projectile weapons.
