Escaping the Ghost Hideout
When you come to, you'll need to pass the defibrillator game. Just hit “E" once the two nodes charge up and flash and you should get fairly close to catching them at the center (unless your reflexes are very good, in which case, wait for them to start moving).
This should take out the bandit leader and let you recover a bit. Walk out the main door and start heading down the hallway. Go ahead and drop down into a crouch when you get the reminder. If you go into the right room, you'll be able to sneak up on a lone ghost inside. If you have wingsticks, use them. Otherwise, just shoot him.
Swing around the corner and get ready to engage a group of bandits outside. These guys all have pistols, so things are about to get interesting.
Crouch behind one of the raised metal walls and fire at the bandits positioned around the area ahead of you. Just watch for their shots and return fire. If you stick behind the metal, you should be fine, since they aren't particularly good shots.
Once you've picked them off, move forward to the next office. When you get inside, watch out for a rusher and two pistol users that will take cover behind the desks. Fire from the hip to take out the rusher as quickly as possible, and then get behind a desk or vending machine to kill the others. Take out the last rusher and push out to the center. Use a wingstick on the distracted guard, grab the grenades next to his body, and then walk out to the next balcony.
Take the chance as you walk by to watch for men in the courtyard below. They can't really shoot you that well from down there, but you can position yourself so that you can get a few good shots. If you can, pick a few of them off to make the next section easier.
Advance through the building and move down a level. There will be a couple of HE grenades lying on a table if you want them. You won't really need them to get out, but it's good to have extras.
Shoot the two guys lying in wait for you by the exit, and then move out into the main courtyard. Hopefully, you've cleaned it up a bit from above. Use the doorway for cover and shoot your way out. If you didn't get a chance, then a grenade will really open things up. Move up to a fallen pillar and then punch through to the catwalk. Move up to zipline and jump on it to wind up back at the start of the level.
Just walk out the main door and jump back onto your ATV. You've killed enough ghosts for now, so just head back to the town and report your success to Dan.
While you're here, grab Dan's collector card off the end table next to the wounded man.
