Aiding the Outcasts - 20 pts
Once the DLC is installed, you may have to move around a bit before it kicks in. Try entering and leaving a building or two and eventually you'll get a message that the Pip-Boy has picked up a new radio signal. Once you pick up the signal, you'll hear that some Brotherhood of Steel Outcasts are in trouble and "Aiding the Outcasts" officially begins.
The quickest way to get to the Outcasts is to fast travel to the Red Racer factory and then follow your map marker to the Bailey's Crossroads Metro station. The stairs into the station are blocked with rubble, so instead enter the door as designated by your compass. There are a few feral ghouls in here, so either kill them, or avoid them using stealth or the Ghoul Mask. After you move through the station you'll come up at Bailey's Crossroads proper. Here, the Brotherhood Outcasts are fighting a bunch of Supermutants, so lend a hand as you see fit. The usual mix of Supermutants, Brutes and Masters are here, so take them out as you've been doing. Follow the Outcasts to their outpost, killing Supermutants along the way until the areas are all cleared out. At this point, you'll be told to enter the outpost proper and go speak to Protector McGraw within the outpost.
Get into the freight elevator, leaving any followers behind, and head into the outpost. Once in the outpost, you'll be greeted by Defender Sibley who seems to hate you with every fiber of his smug, arrogant being. He'll take you to talk to McGraw. McGraw will explain that there's a huge armory within the outpost, but the door is locked, and can't be opened until someone successfully completes the Operation Anchorage simulation. The only problem is that they need a Pip-Boy to interface with the simulation and oh, look at that, you just happen to have a Pip-Boy on you. What luck. McGraw makes a deal with you. Open the door to the Armory and you can take whatever you need from it. Obviously, you'll have to agree to the deal in order to proceed.
Once done talking to McGraw, follow Sibley to Specialist Olin, who is as equally unpleasant about things as Sibley. She'll give you a Neural Interface Suit which you'll have to put on in order to interface with the simulation. Put the suit on, open the simulation pod and take a seat in the chair. You'll be whisked away to a magical, wintery wonderland of potential explosive death, and the "Aiding the Outcasts" achievement will pop.
The Guns of Anchorage - 20pts
Welcome to Alaska! It's cold, and people are shooting at you. Fun! As soon as you warp in, you'll be addressed by Sgt Montgomery, your constant companion in this little journey through frigid military service. He'll tell you that it's up to the two of you to take out three artillery guns currently pounding American forces and that he'll meet you in the Chinese Artillery Outpost. He then promptly starts doing his best Spider-Man imitation by scaling a sheer wall of rock. Kind of creepy, actually.
Seeing how you don't have the Wall Crawler perk, you have to take the scenic route. For your travels you have a silenced Chinese pistol, 50 rounds of 10mm ammo and a Stealth Boy. One Stealth boy may not seem like enough, but if you beat feet and don't dawdle you should have enough time to take out all of the guards along the way to the cavern before it wears off. If stealth isn't your thing, then just kill everyone in full view.
However you decide to do it, make your way to the cavern. Once inside, you'll have a couple of firefights before Sgt. Montgomery comes in through the ceiling and reunites with you. Make your way back outside, and shortly after going outside, you'll see a large white pipe with a soldier on it and a room at the other end. Take out the soldier, cross the pipe and go into the room. Your first suitcase is behind the locked door in this room.
After nabbing the suitcase, go back over the pipe and continue along the path taking out Chinese soldiers as needed. Eventually you'll come to a small cable bridge followed by a larger cable bridge. At the end of the larger bridge is a locked door. Behind the door is a room with your next piece of intel. If you don't clear out the Chinese soldiers before entering the room, the soldiers will follow you in there, so be prepared.
Keep on pressing forward and you'll get to the Artillery Outpost. Take out everyone and enter the large building in front of you. When you first enter, you'll see a couple of sets of stairs in front of you. Go up all of the stairs, taking out soldiers as necessary. Eventually you'll enter a room with an overturned table and a Chinese Assault Rifle behind the table. Take the hallway to your east, and after the hallway takes a 90 degree bend, there will be a locked door to your west. Through this door is your third piece of intel.
As you press forward you'll eventually come to a room with a drop off to your right and some Chimera tanks. Montgomery will make a comment about the tanks. Keep an eye out for a terminal and a table with a bunch of ammo on it. Next to the terminal is a door. Behind the door is your fourth piece of intel and the last piece of intel you'll find in this mission.
