This heavily fortified complex was used by Doctor Orona in 2193 as a safe haven for the ever advancing Xenomorph infestation on Earth that started the year before. During the later half of that year, Orona, now seeing the error of his ways in trying to harness the hostile spieces as a weapon system decided that he would stay on the planet as others fled. During this time the complex was compromised as Orona made a transmission regarding his revelation with the hordes banging and clawing through the blast door. After Orona spoke his mind about the folly of his ways, he pulled out a pistol and put it in his mouth and pulled the trigger, killing himself before the creatures could take him alive.
