After moving the boat closer to the STOREROOM landing and collecting the FIRST FUSE, as described earlier, return to the POOL by following the wide tunnel to the east.
Continue through the CAVE WITH THE DANGLING BUILDING and straight out the other side.
When you reach the ledge with the striped barricades, drop into the water below.
Swim across the POOL and climb onto the small boat, which you moved earlier. Take a running jump from the boat to the ledge with the wooden crates.
Climb over the one on the left.
Here you'll find a small room packed with "Natla Technologies" crates. Pick up the magnum ammo (4) inside on the left.
Find the movable Natla box (it's slightly darker than the others) and pull it once.
Go around to the right and push it into the space where the ammo was.
There's another movable box behind the first. Pull it twice. Go around to the right and pull it again to open up the passageway behind it.
Enter and use the switch...
...to move the drill car back in the cave to the south.
Return to the POOL, swim to the left (south), and climb out on the ledge with the barrels.
Follow the passage to the drill car, which you just moved so it's no longer blocking the tunnel.
Go into the tunnel and push the Natla box twice.
Go around it and continue forward.
Where the passage widens, move forward carefully and pick up the SECOND FUSE (5), which is lying on the ground. Don't go any farther...
...or you'll attract the attention of the cowboy lurking ahead on the right.
NOTE: If you do accidentally activate the cowboy before retrieving your pistols, it's OK. Just run back the way you came, and continue following the walkthrough. The cowboy should soon lose interest and return to the cave where he spawned. You can then deal with him later.
DARK MODE: Even with brightness adjusted, dark images on a light background can be hard to see. May I suggest a reputable dark mode browser extension, such as Dark Reader? (Download only from trusted sites, like darkreader.org or your browser's web store.)
