Welcome to Base Approach. Look for a relic right by your fire.
Around the first corner are four guys, and a spotlight. Take them out by bow from a distance, and then avoid the light to enter the building. There are three more guys inside, at least two of which you should be able to get the drop on.
Across the way there are two more guys operating the spotlight. On their platform, all the way around, look for a GPS marker. Then head up and to the top of the tower, and take a rope into the base.
You’ll immediately here some guys talking. They’re next to a barrel, and you should feel free to shoot it and make it blow up. However, if they burn, you can’t loot them. A third guard will show.
Move on and look for an opening on the right. Go into it, and turn right to find some loot and a barrel. Light your torch at the barrel. Return to where you blew up the guys, and look for a room on the left. It has a fancy rug on the floor. Use the torch to burn the poster on the wall. Follow the crawlspaces.
Now the logic in the next bit might be a bit iffy. There is a room you have to crawl in with a valve. As soon as you open the valve the room will fill with gas and you’ll draw the attention of a bad guy. Jump up and get out of the room you just entered. Pick up a lantern, and throw it THROUGH the little opening you just came out of.
On the other side of the explosion, you’ll get a new gun. Through the next door, look for a document next to some ammo.
You’ll be glad for the new gun, as in the next section, you’re gonna have to kill a lot of people. Fast. After that, you’ll find a tunnel that leads to a control room. After a cutscene, look in the room for ammo, a document, and a banner to burn. Look for a hole in the wall with an arrow by it to continue.
Part 6: The Radio Tower (2/2)
Back outside, look for a fire to upgrade if you’ve got the loot to spend. You’ll cross a bridge, find a QT event, and then face a LOT of guards. They don’t come all at once, but many of them are elevated, so take your time. Keep an eye out for loot while you’re at it.
Climb up to a small tower and you’ll face off another handful of guards. Drop down into the courtyard, and you’ll face your first really challenging guy, kind of a mid-boss in SWAT armor. You’ll learn to dodge. Switch to the machine gun to stitch him up fast when you have an opening.
Look for a locked door in the building for a relic. There’s a document by the next campfire, too, which will allow you to fast travel if you want to backtrack for anything right now. Then, grab the rope and cross over to the tower. Then head on up.
Slide off the tower down into the courtyard. Look for a firestarter in the building, pick it up, then open the gas valve, and light that mother up! This will lead to a very extended action/dodge sequence, first sliding, and then running. When running, look for white boards as safe places to jump and land.
At the far end of your epic run and jump session, you’ll meet another bad guy with a shield, so get your dodging thumb ready! After that, a campfire and some story.
Now we’re gonna learn you a new trick, shooting with a rope arrow. This may bring some other tricks to mind for going back and revisiting areas, so keep those in mind. Take out the guys in this next section, then use the rope arrow to pull a crate free and climb up and on.
The rest of the path is very clear, just keep moving until you meet up with your mentor.
After that, you’ll want to fast travel back to the Mountain Village. Now that you have the rope arrow and the flint, climb the nose of the crashed plane and ascend a new area.
As you ascend, you’ll run into two bad guys that you can sneak up on. Then cross via another rope bridge, There’s a lot of space to explore here. Look for a nest on a ledge for another collectible. You’ll also pass another Unknown Tomb.
