Go deeper into the station by crossing through the trains in the area and reaching the stairs that will take you to the other side of the platform.

2. Open the Shortcut to the Entrance

Open the gate to create a shortcut from the entrance. We recommend doing this before moving past said gate, as you're bound to encounter multiple strong enemies that can easily take you down.

3. Defeat the Hanging Naytiba to Proceed

In this mission, you'll encounter a type of Naytiba that can block your path by hanging on the walls. You will encounter more of these along the way, so keep an eye out for other blocked areas.

Continue proceeding through the end of the station after defeating this Naytiba.

5. Proceed to the Railway Tunnel

Once you've unlocked the camp, move towards the railway to get to the next area. However, be careful because the train in this section will suddenly move and can kill you instantly.

6. Obtain the Landfill Passcode

Once the train has stopped, hop on it to get through a path on the right. Continue down this hallway, and you should see a fallen Legionaire at the end. You can get a passcode you'll need in the next area from this corpse.

Inside the Landfill gate, you'll see a number of tough Naytibas lurking near a supply box. You can take them head-on, or you can climb on the ledges to the left and perform an Assault dive to instantly take down one of them—preferably the toughest among the bunch.

After dealing with the enemies, open the supply box using the passcode you got earlier to obtain a Fusion Cell.
