This new, relatively unknown parasitic
species of life form, is considered the most deadly.
The Xenomorph life-cycle begins with an egg, layed by a Queen. From
this egg hatches the first stage, an aptly named "facehugger".
The facehugger, which looks like a walking "hand" - with eight
legs and a tail - which hunts down a living being, and attaches itself
to the face or other bodily orifices of the prey. It then secretes a
chemical to sedate its prey, and proceeds to implant an embryo into
the new "host". When impregnation is complete, the facehugger
falls off and dies. Eventually the host recovers, and is able to resume
normal operation. Over time, the host will experience hot flashes, body
pains, and other flu-like symptoms, as the parasitic alien inside it
grows and develops. When the parasite matures, it begins convulsing,
attempting to claw/puncture its way out of the host. The process usually
kills the host. After "birth", the alien is small (depending
on the size of host), and will grow to become an adult alien, with traits
similiar to its host. The adult alien is a deadly, efficient drone,
which works on aquiring other hosts for the facehuggers of its hive,
building the hive, and protecting the queen. On occassion, a queen alien
is born, which will grow to a larger form, and be capable of reproduction
by laying eggs.
Xenomorphs are the deadliest fighters in hand-to-hand combat, being
extremely strong and agile. Their speed is extroirdinary, their sheer
strength and instinctive killing ability unrivaled. They are, without
doubt, the ultimate killer.
are organized in a caste structure within the hive. There is a single
queen alien, which lays the eggs for Facehuggers. There are several
castes of alien, including drone workers, warriors, and "royal
guard" - the best fighters, which guard the queen and the center
of the hive, where all the eggs are. The warriors defend the hive and
drones, which collect hosts and bring them alive to the hive, and imprison
them in resign near eggs which are near ready to hatch.
Although strong, xenomorphs are generally fragile. A single well-placed
pulse rifle shot can kill a xenomorph, although the difficulty in making
such a shot is extreme. Xenomorphs work best when attacking in swarms,
since they have no ranged combat and must get in close. However, in
cramped close quarters with
little or no ability for ranged combat, a single alien can tear through
a group of humans.
