The Wright-Aberra fuel depot was a large, midspace fueling station used to refuel mass haulers, colony ships, and anything that burns a lot of propellant escaping its home gravity.
The fuel depot is massive in size. It contains short-stay housing, food service, a security force, storage bays, and multiple common areas that facilitate hundreds, maybe thousands, of people. The station was kept at about point eight Earth's gravity.
In 2138, a colony hauler came into the fuel depot packed with infected refugees from a conflict zone. The Xenomorph infestation spread to common areas and on into other ships in berth. Three ships took off while the rest were held back.
Stolen data from Weyland-Yutani flagged this space station as a possible contagion breakout point. One month later, while looking for survivors in the Alien-infested fueling depot, Zula and Davis discovered a lone medical officer, Dr. Hollis, hiding in the bowels of the station.
However, they are not the only ones, who are here. The Weyland-Yutani's team (24 Colonial Marine, and at least three Wey-Yu employee) arrived with a Conestoga class ship. The Company's team board the station via a Dropship, their goal is to capture Xenomorph samples (not necessary live specimens, some body parts could be enough). Zula, Hollis and Davis set loose the isolatated Aliens, to cover their own escape (they tought that the marines are after them, not for the specimens). The marines first try to capture some Warriors, via electroshock bullets from an M56 Smartgun but they fail miserably. While the soldiers shoot down multiple Xenomorphs, and obtain an upper Warrior body but they also suffer high casualties.
Meanwhile Zula and Davis learns the plan of their enemies, so they launch a torpedo to destroy the Marine's Dropship. After this, Hollis opens the oxygen containers and set on fire the fuel containers, making the station to a giant bomb. While Zula and her two partner escapes with the Europa, the remaining soldiers and Aliens are not that lucky, all of them dies during the explosion.
