the liberation of the planet on February 21, 2108 by building an escape vehicle out of scrap parts.
Subsequently, Parker was honorably discharged from military service and returned to Earth. Late in
2109, Parker began studying at the San Diego School of Astro-Engineering, but dropped out of
studies on March 29, 2113. On October 2, 2113, Parker started working as a freelancer for Mex-
Corp until January 7, 2114, when he accepted an assignment at the United Americas lightspeed acceleration
threshold on Neptune. He eventually returned to engineer duty aboard space vessels when
he entered Weyland-Yutani employment as Assistant Engineer aboard the cargo vessel Otago on
May 5, 2115. Two years later, on October 27 2117, Parker began service as an engineer with a flight
status rank of C aboard another cargo vessel, the Nonnabo, where he would meet and develop a
friendship with Brett. Together with his friend, he joined the Nostromo en route to Thedus on
September 10, 2120. He would remain on the ship to be involved in the Nostromo incident two
years later.
Parker was responsible for repairing minor damage on the Nostromo together with Brett so that it
could depart LV-426 after the discovery of the derelict. During the incident, Parker played a vital
role in assisting the fight against the Xenomorph by developing a makeshift flamethrower, a cattle
prod and a motion tracker, but also suffered a heavy loss when Brett was killed by the Xenomorph.
He would later help save Ripley from a vicious attack by Ash and was among the last three survivors
of the crew, who decided to set the ship on self-destruct and escape in the emergency shuttle.
Parker proceeded to load the Narcissus with oxygen tanks together with Lambert and was killed by
the Xenomorph when he tried to save Lambert from the creature. (A1)
Patna: A modified Conestoga-class space transport operated by Weyland-Yutani. Michael Bishop
used the Patna to travel to Fiorina 161 in 2179 in a failed attempt to secure one of the two Xenomorphs
involved in the Fury 16 incident, being the fully-grown Runner and the Queen embryo gestating
inside Ripley. The Patna was reportedly equipped with advanced medical facilities sufficient
to perform the extraction of a Xenomorph embryo although Michael Bishop's account in this matter
during the incident has to be considered dubious. At the very least, the ship must have been sufficiently
fitted to hold and contain a fully-developed Xenomorph specimen. (A3)
PDT: Abbreviation for Personal Data Transmitter. Describes a small device either carried by or implanted
inside a person that transmits locational data like position and distance. This data can be received
and processed for readout by a range of systems, from a mainframe to a small portable receiver.
While a PDT is often used for surveillance purposes, it can also be used to find missing persons.
An example of the usage of PDTs is the colony Hadley's Hope on LV-426. During the Hadley's
Hope incident, the recon mission used the mainframe to locate a large cluster of PDT signals emanating
from the nearby Atmosphere Processor. When investigating the source of the signals, a large
Xenomorph hive was discovered where the colonists had been brought for impregnation during the
Xenomorph outbreak preceding the incident. Later, Ripley gave her PDT to Newt and used it to locate
her inside the processor after she had been abducted by the Xenomorphs during the escape to the
landing pad. (A2)
Perez, Martin Allahandro Carlos: A male human serving as a General for the USM in 2381. Was
charged with overseeing the cloning project aboard the Auriga aimed at harvesting the Xenomorph
for research purposes. Perez opposed the scientists' request to keep Ripley 8 alive after the extraction
of the Queen embryo had been a success. Meanwhile, Perez had struck a deal with the smuggler
Elgyn, with whom he went back a ways, to deliver human hosts to the Auriga. Shortly before
the outbreak, Perez received Elgyn, his crew and their cargo aboard the research vessel. In addition
to hard cash, Perez agreed to have the crew of the Betty as guests for a few days. Perez was later
killed by a Xenomorph during the evacuation of the Auriga after he had sacrificed an manned escape
pod infiltrated by an Alien in order to contain the infestation. (A:RES)
