Once General Petrovsky overhears Aria mention the bunker's location, he sends wave after wave of Cerberus troops to capture it. They are initially held at bay by exterior defense turrets, but while Aria recruits the Talons to her cause, the bunker's main entrance is compromised and sealed off. Aria and her troops vacate the bunker via the access tunnels in order to mount the final assault on the Cerberus-held Afterlife Club to confront Petrovsky.
