The Sinking City 2 Beginner Guide: Survive Your First Hours in Arkham

The Sinking City 2 hands you a flooded city, a casebook and very little else. The opening hours click once you internalize three systems: unmarked investigation, the Safe Room loop, and the crafting economy. Here’s what actually matters.

The Investigation Loop

Cases don’t put markers on your map. Instead:

  • Read locations from case notes — “the hotel on the reef side” means finding Devil’s Reef Hotel on signage and boat routes, not following a waypoint.
  • Pin evidence in the casebook and re-read it when stuck; Calvin only forms conclusions when the right clues are connected.
  • Wrong conclusions are possible. The game lets you commit to a bad read of a case. If a verdict feels under-evidenced, sweep the location again.

The walkthrough hub covers every chapter if a case has you fully stuck — and the safe codes page skips the busywork when you just want the loot.

Safe Rooms: Your Anchor

Safe Rooms are where you stash, craft and save. The rhythm that works: expedition out, fill your pack, retreat, bank and craft. Two habits to build early:

  1. Never expedition with a full pack. Inventory space is scarce; hauling junk means leaving case-critical items behind.
  2. Bank before boss-shaped encounters. Death costs you progress since your last save, and saves happen at Safe Rooms.

The Crafting Economy

Ammo is crafted from scavenged resources, not found on shelves. Practical consequences:

  • Every fight has a real cost. Running from ordinary Drowned is often correct — see the enemies guide for what’s worth shells.
  • Craft ahead of need: entering a new district with an empty shotgun is how runs die.
  • Healing items (Dolorocide Pills) compete for the same resources — don’t burn everything on bullets.

Early-Game Checklist

  1. Open the Apartment 5 safe by the Radio Station — code 1908 — for 14 pistol rounds and a heal. The best free start in the game.
  2. Do side investigations as they appear; some expire at chapter boundaries, and each one pays out gear or Dream Essence for Talents.
  3. Choose silver at the Cursed Press in Chapter 2 (2 Dream Essence beats the shotgun accessory long-term).
  4. Learn weak points early — pistol shots to weak spots kill in a fraction of the ammo.
  5. Set your difficulty honestly. Combat is deliberately scrappy; if you’re here for the detective work, lower combat difficulty is a legitimate choice and affects nothing else.

Common Early Mistakes

  • Fighting everything (ammo bankruptcy by Chapter 2).
  • Ignoring the boat — several districts are quickest by water, and boat routes reveal signage you need for navigation.
  • Skipping optional safes: they’re the main source of weapon attachments. All of them are on the safe codes page.
  • Selling/dropping quest-adjacent items — if it looks like a mask, a plate or a prism, it’s a puzzle piece. See puzzles.
