Functionally identical to the Cyberdiscs of the First Alien War, except miniturised for indoor-use, Bio Drones are terribly dangerous.
The usual Cyberdisc warnings apply here:
1. Use anything other than a Melee weapon against it with cause an explosion big enough to kill creatures nearby... Aliens, civilians, or your men/women.
2. Though it has a front and back, and therefore possible to sneak up upon it unnoticed, it is physically impossible to tell which way it is facing visually.
3. When possible, double-team against a Bio-drone. Have an aquanaut drawing fire, while another sneaks up behind it with a Melee weapon.
4. Bio-Drones leave scorch marks on the ground is they are moving around above sealevel.
The Bio-Drone is a creation only an alien mind could conceive of. It is a brain, (human or alien) suspended in amniotic fluids and connected to a powered base unit that can fly on land or below water.
Each Bio-Drone is armed with a powerful auditory disruptor, part machine and part organism. Some of our scientists have suggested that the weapon is driven by the host organisms original vocal cords. Highly accurate and tenacious these super guard dogs are widely used by the aliens to protect valuable assets.
The hypothesise that the auditory disruptor is a biological device are true. This unfortuanate creature literally screams its enemies to death. Every example has massive surgical trauma scars and is severely mutilated. The aliens appear to butcher the brain into obedience.
Most of the cortex's used in the creatures are alien in origin, but nothing can compare to the horror of finding a human based unit. The Bio-Drones are powered by an ION engine and incoporate some form of remote control system.
