A soft blaring alarm echoed throughout the UAC base, along with gun fire as the usual workday for a UAC employee or security guard began. Under assault by hellish forces. Those who were not fortunate enough to die during the fighting found their bodies tainted and warped as possession took their bodies by force turning them into zombified husks the base falling silent and the radio being jammed preventing any survivors from contacting reinforcements. But the forces of hell are still quite sloppy when it comes to causing their own demise, not knowing when to close their portals as something followed them through as the doom slayer walked through the portal. Praetor armored boots echoing as she walked behind a possessed marine wielding a shotgun, brutally punching her hand through chest. The blade of the suit helping to obliterate his heart as she snatched the shotgun from him taking the ammo as well as she pumped it. Marching into the facility to begin the cleansing.
