The Sinking City 2 Collectibles: Crates, Broadcasts & Outfits

Collectibles in The Sinking City 2 are lean by open-world standards — three chains, two of them achievement-critical. Here’s what to track and when.

Emergency Relief Crates

Locked supply caches scattered through every district. Opening every crate in one playthrough (DLC excluded) earns Behind Every Crate Man… — and since crates hold crafting components, the achievement route doubles as the optimal resource route. Rules:

• Sweep each district before advancing the main story past it.
• Crates are placed along both street and water routes — circle by boat (district guide) to catch waterline caches.

Mushroom Jack Broadcasts

Arkham’s radio voice. Hearing every broadcast in one playthrough earns Mycophile. Stop at each radio you find and let the broadcast finish — leaving a district with unheard radio chatter risks losing it to story progression. Treat radios like crates: part of the first sweep.

Outfits

Calvin has unlockable outfits, changed at Safe Rooms — cosmetic only, no stat effect. Outfits arrive through story progression and the Arkham Field Kit DLC, which bundles three outfits with three Dream Essence and a resource pack (see the DLC guide; it’s included in Deluxe and Premium — editions compared). The full unlock list is being verified; nothing indicates any outfit is permanently missable.

What’s Actually Missable

Missed a chain? New Game Plus is the recovery route.
