Furnace of the Gods - Flooded Passageway and "Defensive Capabilities"
Achievement/Trophy Intro
Picking up the MASK OF TORNARSUK, as shown in the last section...
...also opened one of the doors leading out of the cavern. To get there, turn around to face the entrance, then head for the far right corner.
Go through the door you just opened into a small room with blue stone walls.
If you're hunting achievements/trophies, save the game. The hole in the floor leads to a flooded area with a biting catfish (8). For the "Defensive Capabilities" achievement/trophy, you can't hurt any of the fish or let them bite you. This is challenging if you also want all pickups, but it can be done. Start by turning around...
...and sliding down the slope facing uphill.
When you splash down swim forward just a little, and you'll see the fish spawn ahead. There's a pickup in that direction, but it's virtually impossible to get without being bitten.
So, for now, roll and swim along the flooded passageway in the opposite direction. The catfish should follow.
At the end of the passageway, surface...
...and quickly climb out of the tunnel.
Stay in the ankle-deep water surrounding the hole to avoid spawning many rats (below), that emerge from the low openings when you move onto the dry floor. We'll deal with them later.
Now, make sure the fish has followed you to this end of the tunnel. If you wait too long, it will swim away, and you'll have to take a dip to draw it closer, then climb back out of the water. Save again, since this will probably take several attempts.
Light a fresh flare, drop into the water, and quickly swim past the fish toward the far end of the passageway.
Go as fast as you can, past the vertical shaft where you dropped in, and on to the end.
Swim down into the square hole and quickly pick up 2 bundles of harpoons (9-10) lying on the bottom. (It may help to try and turn around before picking up the harpoons, so Lara is ready to flee by the time the fish arrives.)
Swim up out of the hole, follow the tunnel back the way you came...
...and climb out of the water. With speed and a little luck, you can make it back and forth without being bitten.
NOTES: This is the first of five catfish you'll encounter. My preferred strategy for "Defensive Capabilities" is detailed in a footnote in the main walkthrough. You can, of course, do separate playthroughs for the catfish and all-pickups achievements. If you don't care about either, just harpoon the first catfish when you meet it. Or, lead it along the passageway to the room with the rats, shoot the fish from above, then go back for the harpoons if you like. If you missed the HARPOON GUN earlier, you'll get it here along with one bundle of harpoons.
DARK MODE: I plan to add optional dark mode for these pages, but my current priority is updating the walkthroughs. Meanwhile, 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 official add-on/extension site.)
