"Destroy the Empress. She will not gloat over me."
―Dr. Eisenberg (from Aliens versus Predator 2)

Doctor Arnaud Eisenberg[1] was a research scientist for the Weyland-Yutani Corporation and the director of the company's research facility on the planet LV-1201.

In that time period, Weyland-Yutani had followed the flight telemetry of the derelict ship found on LV-426 and discovered a world full of life and dotted with the ruins of an extraterrestrial civilization—and infested with Xenomorphs. This planet would become known as LV-1201.[2]

The Company established a long-term research facility under Dr. Eisenberg to study the planet, the ruins, and the Aliens.


Early life

Eisenberg was the child of a rich family with considerable sway in Weyland-Yutani circles, as the founders of modern Synthetics. His father was involved in bleeding edge research involving neural imprinting into prosthetic limbs.[2]

First expedition to LV-1201

In 2222, Eisenberg was the only survivor of a disastrous first expedition to LV-1201; when a massive storm cut off his outpost's security systems and communications, he was forced to kill and eat his colleagues. He suffered severe acid burns during a rescue attempt.[2][3] This led to his consciousness being secretly ported into an identical synthetic body using his father's research technology.

Return to LV-1201

10 years later,[2] Eisenberg was in charge of the now extensive research facilities established on LV-1201. He clashed with Weyland-Yutani over management of Xenomorph research on the planet, with W-Y fearing he was more interested in controlling the Hive than the commercial applications they were seeking.[4] Working on LV-1201, Eisenberg devised the sympathetic theory of pheromone relations.[5]

The operation on LV-1201 suffered several setbacks. On September 23, 2230, one of the Forward Observation Pods was destroyed in a mysterious incident.[6] On November 25, the entire Primary Operations Complex was lost when it was overrun by Xenomorphs.[7] Also, Eisenberg frequently clashed with General Vassili Rykov, whose mercenary group known as the Iron Bears was in charge of security on LV-1201's W-Y facilities.[8]

Operation Savior

On January 6, a squad of Colonial Marines arrived on LV-1201 aboard the USS Verloc, sent by W-Y after contact was lost with their facilities due to the Incident.[9] Eisenberg devised Operation Savior, an LMSE designed to simultaneously eliminate the marines and capture the Empress of LV-1201.[10] However, Operation Savior ended in failure when the Empress was freed by a tenacious Drone which also captured Eisenberg.[11]

The Xenomorphs abducted Eisenberg into the Hive, where they dismembered and coccooned him in the Empress's chamber.[11]



  • The fact that he is an android is not known from the start, but rather learned from a few data files in the game, along with the fact that he emits no pheromones (from the player Alien's perspective), similar to the combat androids.
  • Despite being a Synthetic, Eisenberg has the same amount of health as a normal human, so a Headbite, pounce, claw or a well-aimed tail would be enough to "kill" him instantly.
  • Eisenberg is the only example of a synthetic being coccooned in a Hive, despite not being a suitable host for the Xenomorphs. It almost seems as if he was claimed as a trophy. Being a synthetic, he would not die from being dismembered, making his fate particularly gruesome. This also suggests vengeance on the part of the Xenomorphs, torturing him for having threatened the Empress.
