The Sinking City 2 Completionist Time: Collectibles, Documents, and Upgrades

A completionist guide to The Sinking City 2 playtime, including documents, upgrades, room discoveries, puzzles, and a realistic 14–16 hour estimate.

A completionist playthrough of The Sinking City 2 should take longer than a direct story run because many rewards are hidden in investigation spaces rather than placed directly on the critical path. Current length roundups place a thorough run around **16 hours**, with variation based on puzzle skill and exploration habits.

## What adds time?

- Reading documents and connecting clues - Searching rooms for upgrades and collectibles - Revisiting areas after unlocking new paths - Solving puzzles without assistance - Checking the map for rooms that are not fully cleared - Exploring optional paths before returning to the main objective

## The map helps

The review describes a useful room-completion signal that highlights completed areas. Use it to identify locations that still contain a document, upgrade, or clue. This is more efficient than wandering through every corridor repeatedly.

## Do not confuse every item with a collectible

Some objects are resources or progression tools rather than completion requirements. Keep notes on documents, upgrades, and optional discoveries so you do not spend time revisiting a room that has already been fully searched.

## How long should you plan?

Allow 14–16 hours for a careful first run if you want to investigate most areas. Completion times can go higher when a player refuses hints or retries difficult combat encounters, but the available data does not support a single exact number for every completionist.

The best way to enjoy the longer route is to treat each location as a small mystery. Read the evidence, connect the clues, then use the map to finish the rooms that still have something left to reveal.
