The Frozen Chamber 13

Step-by-step walkthrough

1. Visit the lever ledge with Fireboy

   Fireboy walks left up the long lower slope to the dry stretch just below the left tip of the middle bank. Jump straight up before steering right onto that bank. Move to the dry left side of the taller triangular bank immediately above; again rise vertically before steering right over its edge. Cross the frozen basin and step right off its dry bank into the lava corridor below. Walk left across the lava onto the lever ledge, passing through the handle to turn it on.

2. Return Fireboy to the lower floor

   Leave the lever on and walk right along the lava corridor to the spot just beyond the right edge of the basin overhead. Jump straight up until his feet clear the basin’s bank, then steer left onto it. Cross the frozen basin left, continue left past the middle bank, and wait to land on the long lower slope.

3. Climb Fireboy’s right wall shelves

   Fireboy walks right across the bottom lava to the rising floor near the wall. Jump straight up, then steer left once his feet clear the small shelf. Jump right onto the next wall shelf. Again jump straight up before steering left onto the long diagonal ramp. Walk left up that ramp to its dry patch between the ice patches.

4. Hold the upper timed plate

   From the dry patch, Fireboy jumps right onto the higher wall shelf and walks a little farther up it. Jump left onto the high triangular crest, then walk left to the upper pressure plate. Keep him there while Watergirl changes the pool twice; this plate opens the shared shutter beneath both beams.

5. Melt the central pool

   Watergirl moves to the right edge of her starting ledge and jumps right across the upper lava, landing on the dry slope beyond it. Walk right off that slope, then turn left as she drops through the middle chamber. Continue left past the middle bank onto the long lower slope, then follow that slope right to the lower middle plate. Wait for its shutter to open and the central pool to melt.

6. Climb back to the liquid basin

   Watergirl returns left up the long lower slope to the dry stretch just below the left tip of the middle bank. Jump straight up before steering right onto that bank. Move to the dry left side of the taller triangular bank immediately above; again rise vertically before steering right over its edge. Walk right down into the liquid basin.

7. Collect the diamond through the open ramp

   The lever Fireboy visited has already moved the shutter away from the upper-right icy ramp. Watergirl moves toward the middle of the liquid basin, jumps right onto that ramp, and walks up and right to collect the required diamond.

8. Return Watergirl above the upper lava

   Walk left down the diamond ramp and drop into the basin. Near its left end, stand just to the right of the overhanging upper-left slope. Jump straight up, then steer left once her feet clear its tip. Walk left up this slope to the dry bank beside the upper lava. Jump left across the lava onto the starting ledge.

9. Reach the lower-left freeze plate

   Watergirl steps left off the starting ledge onto its lower lip, then left again onto the icy wall shelf. Step off that shelf’s right end onto the rising ledge below. Walk left off that ledge to the next wall shelf, right off that shelf to the bottom floor, then left to the freeze plate. Wait until the central pool freezes again. Keep her on the plate while Fireboy returns.

10. Bring Fireboy down to the central crossing

    Fireboy leaves the upper plate to the right, crossing the crest to the high wall shelf. Step left off it onto the diagonal ramp, right off that ramp onto the wall shelf, left off that shelf onto the small lower shelf, and right again to the bottom floor. Wait on the bottom floor until the timed shutter closes; its signal lasts 5.6 seconds after leaving the plate. Walk left across the bottom lava and climb the middle bank using Watergirl’s two vertical-first jumps.

11. Reach Fireboy’s exit

    Fireboy walks right across the restored ice to its dry right bank. Jump right across the gap onto the red exit platform and wait at his door. The shared shutter is now closed, so Watergirl can later pass the melt plate without changing his crossing.

12. Return Watergirl to her exit

    From the freeze plate, Watergirl walks right up the bottom slope and jumps left onto the shelf above. Walk to that shelf’s high left end and jump right onto the next rising ledge. Move up its dry slope to just right of the icy shelf above, jump vertically until her feet clear it, then steer left onto it. Cross left to the dry dip, jump right onto the lower lip of the starting ledge, and jump right again onto the starting ledge itself. Repeat the upper lava jump and middle-chamber descent, then follow the bottom floor right to the blue exit.

This route was verified in the game simulation using player controls, required diamonds, and both matching exits. It describes this version’s independently reconstructed room, not an official walkthrough.
