Furnace of the Gods - "The Dissolution" Achievement/Trophy

This sequence is also shown in a short video. If you aren't interested in this achievement, or already have it, try the easier alternative here.

After collecting the third secret and climbing back to the top of the volcano, as shown in the previous section, approach the edge of the square pit.

Take a running jump across the pit to grab the top of the ladder on the inside wall. Then climb down almost to the bottom. (You can save the game while hanging on the ladder. Just be sure to hold Action when reloading, so Lara doesn't fall.)

For "The Dissolution" achievement/trophy, you'll need to "break all shattered floor panels over [the] big funnel." There are 9 breakaway tiles below the ladder...

...and 5 more tiles on the other side, near the corner block with the large medi pack (64). In these screenshots, the tiles are numbered in the order we'll break them. The "funnel" below the cracked tiles leads down to the level exit. It's possible to break all 14 tiles in one continuous run—many YouTube guides show how—but we'll pause halfway through on the safe corner ledge.

When you're ready, drop onto the breakaway tiles.

Run forward, then left, staying fairly close to the outer walls as you break the first five tiles.

Then zig-zag along the next three tiles, numbered 6-8 in these screenshots, leaving one tile on this side of the gap intact. You'll need to go fast and make tight turns in order to take a running jump from the 8th tile...

...across the wide gap onto the 9th.

Then keep running, forward and right, over the 10th tile onto the safe corner ledge with the large medi pack (64), the final pickup in the level.

Check to make sure the two tiles indicated above are still intact. You'll need them to reach the exit. If so, you can save again on the corner ledge.

To break the two tiles near the barred window, walk to the edge of the corner block. Take a standing jump onto the 11th tile. Then immediately backflip onto the corner block.

Now face the 12th tile, near the barred window, taking care not to step on the tile next to the corner ledge yet.

Again, jump onto the 12th tile to break it, then immediately backflip onto the corner ledge.

NOTE: If you're having trouble landing on the middle tiles on the far side of the gap (i.e., 9 and 10), it's fine to aim for the left ones instead (i.e., land on 11, run forward and right, over 12, then 10, to reach the safe corner ledge. Then jump onto 9 and backflip into the corner. (screenshots)

When only the last two tiles remain, take a running jump across the 13th tile to land on the 14th, and stop.

The last tile will collapse, and Lara will fall onto the slope and slide into the funnel.

The achievement/trophy should unlock as you slide down the long slope below.

Continue sliding for quite a while before finally touching down in a barred walkway. Run forward into a cage, where you'll get a glimpse of the next level.

Drop through the hole in the floor then step forward to end the level.

NOTE: If you're working on the "Defensive Capabilities" achievement/trophy (catfish avoidance), save the game at the beginning of the KINGDOM level. Reload the save you made earlier in the FLOODED RUINS. Then follow the achievement guide here.
