As the player arrives from Garbage, an NPC quickly enlists him/her to assist the Loners in their fight against the invading military strike force. Start running forward toward Research Institute: North to activate the assault cut-scene, the main mission chain will then change.
Mole is pinned down in the east building of the complex. The only task the player will have is to save him at the present moment in time.
Once control is regained, continue to head forward till you reach the front gate. Duck down and head to the left with the Loners to the side road.
Note: Around 4 to 5 soldiers might still be alive on the other side of the train yard. If the player wishes to keep as many Loners alive as possible, it might be a good idea to help dispatch them first.
Down to the left another 5 or so soldiers will be fighting the player and the Loners. Help dispatch them as soon as possible. Continue forward and head right, into the backyard.
A few more soldiers will more than likely still be around the yard, kill them, then wait for Mole to walk down and start his dialog. After this is done, he will lead the player to the next destination.
This area is the perfect opportunity to become friendly with the Loner faction fast (if the player has enough Medkits). If the player is lucky enough, when the Loners are being shot they will sometimes become injured instead of killed and fall to the ground. Quickly run to downed man and offer them a Medkit. Within a few revivals the faction should become friendly towards the player.
The area is not repopulated by Loners as happens in the Base Game, although bandits may wander into it later.
The Supply cache #1 can be found on top of the center building in the complex (once the coordinates have been found)
The Supply cache #2 can be found underneath the bed in the east building where was Mole is held up (once the coordinates have been found).
An occasional Bloodsucker will also patrol the location.
