Alien
VEHICLES

Cyberdisc
This miniature flying saucer is an automated terror weapon armed with a powerful plasma beam. The anti-grav propulsion gives it a big advantage in difficult terrain. Its primary function is destruction and terror in the service of the Sectoid race.
Cyberdisc autopsy:
The Cyberdisc is well shielded and is particularly good at withstanding explosive ammunition. The primary anti-gravity system is too badly damaged to gain any understanding of its functioning.
Sectopod
Sectopods are robot creatures with a powerful plasma beam weapon. The control of these mechanical beasts is via a telepathic link to their controllers, the Ethereals. Sectopods are the most powerful terror weapon available to the alien forces.
Sectopod autopsy:
The robot is sturdily constructed with powered armour capable of resisting most forms of attack, in particular plasma weapons. However, the sensing circuitry seems particularly vulnerable to laser weapons.
