The Sinking City 2 Trophy Guide and Platinum Roadmap

Run one: story and everything reachable

1. Play at a difficulty you enjoy. No trophy forces Sleep Demon, and you can change setting mid-run.
2. Pick up every clue. Evidence funds Dream Essence, and several trophies sit on optional investigations that need it.
3. Open every ERC crate. Track pens against crates — a spare pen at a chapter's end means a crate went unopened.
4. Run the missable checklist before each point of no return.
5. Do the optional content. Holloway Manor if you have the Premium Edition, and every side investigation you find.

Run two: Ex Oblivione Mode

Finishing the story unlocks Ex Oblivione Mode. You keep progression, which makes the combat trophies easier, and the codices finally exist.

• Codices first. They are the only genuinely NG+-exclusive collectible.
• Fill talent gaps. A single run does not generate enough Dream Essence for everything; the second run closes that.
• Mop up missed sets. Anything a closed chapter took in run one.

A realistic time budget

The 20-hour platinum figure comes from trophy-tracking sites rather than Frogwares, so treat it as a community estimate. The story-length range is well corroborated across reviews — see how long the game takes.

Should you chase the platinum at all?

It is one of the friendlier survival-horror platinums of the year. There is no locked hardest difficulty, no timed challenge run, no online component, and the game is short enough that two playthroughs total roughly the length of one modern action game. The only real demand is attention: sweep each chapter before it closes.

The one thing that will cost you a third run is carelessness on run one combined with carelessness on run two. Keep the checklist open both times and 100% lands comfortably inside the reported 20 hours.

The three traps

• Assuming you can go back. There is no chapter select. This is the trap.
• Hoarding Dream Essence. Unspent essence does nothing. Buy talents as you go — which first.
• Skipping optional investigations. They are the main essence source and several trophies depend on them.

Platform differences

The platinum exists only on PlayStation. On Steam and Xbox the same 23 unlocks are achievements with no tiering, so "100%" is the equivalent goal. The route is identical on all three.

One platform quirk is worth planning around on PC: Steam Cloud saves sync between machines, which makes a two-run completion easy to split across a desktop and a laptop, but it also means a corrupted local save can propagate. Before a long collection session, it is worth letting the cloud settle before you start rather than closing the game mid-sync.

If you are hunting on PC, two practical notes: connect a DualSense over USB rather than Bluetooth for full feature support, and check the crash fix page before a long session — Frogwares' own troubleshooting steps prevent the most common interruption.

Treat this page as the completion guide and the trophy list as the reference: one tells you what exists, the other tells you the order to do it in. Used together they are a full 100% achievement guide without spoiling the story beats that half the trophy names give away.
