Commander Liam Hadden was the leader of the security forces at the Primary Operations Complex during the incident on LV-1201 on September 25, 2230.


As the Xenomorph infestation at the POC began, Hadden was initially reluctant to notify General Vassili Rykov, believing it to be a single contagion at first. By the time the infestation had spread, it was too late for Rykov to reach the POC in time. Hadden also ordered to notify Gateway Station, but Dr. Arnaud Eisenberg had the transmission cut to prevent his superiors from finding out what was happening on LV-1201.

Hadden was reported dead by Level 4 Security Guard Joss Blaney on November 28, 2230.
