In this part of the No One Left Behind mission, you'll sneak into the Solarii Stronghold. Get ready to cross rooftops and bridges while dodging enemy fire, and work with Roth to find a way into the fortress caves.

Crossing the Initial Rope Bridge

Once you've picked up any collectibles from fallen enemies, take the zip-line. Go up to the top floor of the eastern building. Find the rope bridge and cross to the eastern ledge.

Keep climbing even if enemies show up—they'll cut the rope, so be ready to hit the action button so Lara can grab the wall with her climbing axe. Then, head to the northern building and look for a hole in the wall to slip through.

Ascending Inside the Building

After you get inside, climb up to the higher ledges. Soon, you'll be under a bridge with guards above. Jump from here to the interactive ledges, pressing the action button when needed.

Move right to enter a small tunnel under the walkway. Be ready to press the action button again when Roth starts shooting at the guards above.

Traversing the Beams Under the Bridge

Go as far right as you can in the tunnel, then climb onto a wooden beam. Jump to the next beam and climb up. From here, the path is simple.

Grab the left edge of the structure and move right, listening to Roth's instructions. Stop when he tells you so he can safely take out the guards.

The Bridge Assault and Escape

Once Roth takes out the last guard, try to climb onto the bridge. This will start a cutscene where Lara fights a guard. When she pushes him off, be ready to press the action button.

Start climbing again right away. Lara will come under heavy fire, so keep running forward. Jump onto the hut's roof, turn right, and jump again.

Keep moving, then jump to the ledge above and use the climbing axe to reach the top. This starts a conversation with Roth and earns you 100 XP.

How to Get to Vista Tower Base Camp

Jump to the ledge ahead to get started. Keep going straight until you reach Vista Tower, the new base camp. Take a short break here.

Then, go north and cross the broken wall, jumping over any gaps. Listen to Roth's advice. Finish the climb to reach a safe ledge, which will trigger another chat with Roth and give you 200 XP.

Entering the Caverns

Now you're in the Cavern Entrance. Follow the path ahead. You'll come to a partly flooded hallway where you need to swim. Keep going through this area, and new objectives will appear when you reach the next section.
