The Sinking City 2 Achievements & Trophy Guide: All 23 Unlocks

The Sinking City 2 ships with 23 achievements (trophies on PS5). The list splits cleanly: story progression, the eight optional investigations, two single-playthrough collectible chains, and completion caps. Here’s the full list with what each actually requires.

Side Investigation Achievements

Each of the eight optional cases has its own unlock — these are the ones players miss by rushing the main story:

AchievementRequirement
The InheritanceInvestigate the wall safe — Apartment 5, code 1908
The Other GodsInvestigate the church mystery — the Trident & Obelisk case
The Siren’s CallInvestigate the alluring song — Devil’s Reef Hotel, safe 2137
The Red PressInvestigate the cursed press — Printing Plates puzzle
The WhisperersInvestigate the brain machine — Wireless Room, 13-05-36
The VaultInvestigate the locked storage — hospital basement, 1308
The DrownedInvestigate the mysterious locker — Buoy Locker, Ezekiel case
The DamnedInvestigate the sixteen punishments — Roman numeral door, then kick the green figure in Salt Storage

Warning: some optional cases close at chapter boundaries. Clear each one in the chapter where it appears.

Single-Playthrough Collectible Chains

Two achievements demand a full sweep in one playthrough — the real completionist threats:

  • Mycophile — listen to every Mushroom Jack broadcast in one playthrough. Broadcasts play at radios as you progress; if you leave a district with an unheard broadcast, it may be gone.
  • Behind Every Crate Man… — unlock every Emergency Relief Crate in one playthrough (DLC excluded). Crates are locked supply caches around Arkham — open every one you see.

Missing either means a New Game Plus lap — see the NG+ guide.

Story & Completion

The remaining unlocks track main-story beats — from Welcome To Arkham! at the start through Timeless Dawn and From Oblivion in the endgame (the latter a nod to Lovecraft’s Ex Oblivione) — plus:

  • What Dreams Are Made Of — obtain all Talents. Prioritize Dream Essence income all game: take silver at the Cursed Press, clear side cases. Details in the Talents guide.
  • For Her — unlock all other achievements. The capstone.

Fastest 100% Route

  1. Play chapters in order, clearing all eight side investigations as they appear.
  2. Open every Emergency Relief Crate and stop at every radio for Mushroom Jack.
  3. Take silver at the press; funnel Dream Essence into Talents throughout.
  4. Finish the story, then use NG+ for anything missed and the alternate ending.

Estimated completion: one thorough 12–16 hour run plus a short NG+ cleanup.
