Hell Is Us is filled with some genuinely intricate puzzles, some of which can be incredibly challenging to solve. While for most of these puzzles, you do get hints from NPCs or notes scattered across the vicinity of said puzzle/locked door, the same cannot be said for the cave door in the Mists of Plains. It’s one of the final puzzles that you need to solve in Hell Is Us, and it is easily the most frustrating, simply due to the lack of direction.

Thankfully, the environment does hold clues to solving the puzzle. However, it’s not easy to find the answer to this particular puzzle unless you explore every nook and cranny of the location. Here’s a comprehensive guide on how to unlock the cave door in Mists of Plains, in Hell Is Us.

Mists of Plains is one of the last few areas in Hell Is Us that unlock as part of the Keystone of Ecstasy questline. You can essentially reach the Mists of Plains automatically by following the Ecstasy questline and completing the Lethe and Jeljin locations. However, do note that the Mists of Plains is one of the few Grade 3 locations in Hell Is Us, with the other being Jeljin. As such, this area is filled with enemies of Grade 3, which are significantly more challenging and tankier. Thankfully, you can easily defeat the Grade 3 enemies by upgrading your weapons to at least Grade 4 and hitting Level 16 (experience).

The Mists of Plains is a fairly straightforward location with very few points of interest. There’s one Timeloop, and that’s about it. The only other things in Mists of Plains (apart from the Timeloop) are the two pressure plate puzzles. However, before you can reach those puzzles and the Timeloop, you need to unlock the door locking the path to progression.

To unlock the cave door in Mists of Plains, you need to interact with the rotating lock and set the correct sigils in the lowermost column. However, the game doesn’t give you any direct hints at the correct sigils that you need to use. Instead, you need to explore the opening area of the Mists of Plains to find the correct sigils that you need to use. We highly recommend defeating all the enemies in the opening area to make it easier to find the solution. You essentially need to look for the big statues with the twin serpent symbol on top.

Make your way to these statues and look for the sigil that is etched on them. Take note of both the sigil and the outline shape. The solution to the cave door is: Sword (Pentagon) > Diamond (Square) > Sun (Circle) > Eye (Tilted Square).
