Aiding the Outcasts

Aiding the Outcasts is a Fallout 3 quest that was added to the game in the Operation: Anchorage downloadable content pack.

The Brotherhood of Steel Outcasts are trying to acquire advanced military tools, and the only way to enter the vault containing these relics is by completing a military simulation only the player can enter. In the simulation the player fights in one of the greatest battles of the Fallout universe: the liberation of Anchorage, Alaska from invading Red Chinese troops.

Investigate the Outcast Distress Signal
After installing the DLC you receive a message about an Outcast Distress Signal and this quest is added to your Pip-Boy.

From the emergency signal you learn that Defender Morrill is asking anybody capable of receiving the signal for support at Bailey's Crossroads.

Bailey's Crossroads can be reached via Bailey's Crossroads Metro just south of the Red Racer Factory. This is a fairly standard tunnel system occupied by a few feral ghouls.

Help the Outcast soldiers
At Bailey's Crossroads a battle is taking place between Super Mutants and Brotherhood Outcasts. The battle progresses through a building until you reach the Outcast Outpost guarded by Mark IV Turrets. Once there Defender Morrill who led the Outcasts to the Outpost asks you to speak with Protector McGraw at the bottom of a Freight Elevator.

Talk to the leader of the Outcasts
Arriving at the bottom of the elevator, you are greeted by Defender Sibley. Not too happy to see you, he asks you to keep your mouth shut and follow him. He leads you to McGraw who explains that there is some high-tech equipment locked away and only you with your Pip-Boy can complete the VR program and gain access. This VR program is a simulation of the Anchorage Reclamation with safety measures disabled, death in the simulator means death in the real world as well. The Protector asks you to follow Sibley to Specialist Olin.

Explore the VSS installation
Olin can be found in the room with the simulation pod. She hands you a Neural Interface Suit which according to her is required to be able to participate in the simulation.

Enter the simulation pod
Once you put the suit on, open the simulation pod and activate it this quest is concluded and you find yourself inside the simulation, at the beginning of The Guns of Anchorage.

Bugs
Sometimes when entering the simulation your follower will die so fire them before hand to be careful.
