Resolve one Mystery. Mysteries are Hell Is Us's signature investigations — you gather clues, notes and testimony and piece the answer together yourself (no waypoint tells you). Solve your first and it pops; it also teaches the loop for Super-Sleuth.

Resolve ALL Mysteries. The completionist investigation trophy. Because there are no markers, read every note, listen to every NPC and keep your journal in mind; each Mystery is solved by acting on the right clue in the right place. Do them as you explore each region so you don't have to reconstruct context later.

Solve 25 puzzles that require the right item. Many doors, mechanisms and Vaults need a specific found item to open. Twenty-five such item-gated puzzles across a full playthrough is comfortably reached if you engage with the world's locks rather than skipping them; cumulative, so no need to track individually.
