Bridger's Map & Kirk's Goodbye

After gathering the calling cards for the Georgetown Sniper, Tiny Saul, and Gary, head back to Bridger in the Eckington Camp. Talk to her and she will give you another voice-line. Don't worry, like earlier if you miss it or she doesn't say anything, you can still complete the quest. Head to the office next to her and inside you'll find an item called Bridger's Map. Head out and check it out in the main menu. It is a crude drawing but shows exactly where you will find the final item. The mission you are heading to next is "The Last Stop" which are the tunnels you use to escape after surviving the attack on the Anderson Camp.Go to the Last Stop. It is also recommended that you do this with a friend for a reason that will be apparent later. Make your way through normally (once again), passing the train after lifting it up and heading into the area with a locked door and a coded puzzle. You will need to flip certain switches around this area that coordinate with a doorlock in order to get to the next area. The switches are all around the place but be careful as there are trap doors scattered randomly and a plethora of zombies. Like "Listening In", this area also has a route that instead of taking you the normal way, you are taken on a path that leads you through an emergency exit. If this happens,You have to restart. After opening the door drop down to the left and start heading towards the center of this subway stop, making your way through a water-infested area. You'll see a bunch of camping tents and equipment laying around which gives hints that this was formerly the camp that Bridger resided in. Once you are in the middle of this camp, head left and you should eventually run into a fence and a locked door. The lock on this door is RNG, and can be something that you don't have, and may require something like a lockpick, even if you only have a chemical kit. If you are playing solo and it is not the right lock for you to open, you simply have to restart. If you have someone with you however, you can merely have them leave, switch out for the appropriate item, and return back to your game.
