Alien Quarantine Labs
|Alien Quarantine Labs|
Xen Aliens brought with the Displacement Beacon are studied in the Alien Quarantine Labs. There can be found a partially dissected Headcrab, a headless Zombie, venom sucked out of a partially conscious Bullsquid (the machine to which can be operated, causing pain to the creature), an Alien Grunt in a tank and a dead Vortigaunt with its slave collars hooked up to a large power device, which, when turned on, reveals that the collars play an important role in creating their lightning bolts.
During Decay, Gina Cross and Colette Green are sent there by Richard Keller from the Gamma Labs to turn on a beam matrix to power the Displacement Beacon on the surface. The matrix consists of three primary-colored lasers that have to be combined and sent through multicolored Xen crystals to give power to the Beacon located above. As usual, the place is swarming with the common Xen creatures, added to the creatures already studied there.
