The Sinking City 2 Chthonic Arsenal Weapons

What the three guns are

They fill the same three roles as the early campaign guns in The Sinking City 2, which is exactly why they are useful: having a shotgun before the game intends you to have one smooths the difficulty spike in chapters 2 and 3, before talents come online.

Are they worth using?

Early in The Sinking City 2, yes — particularly the shotgun. Later the distinction stops mattering, because ammunition economy decides your loadout and you will settle on two guns regardless of which shotgun it is.

What they do not do is make the campaign easier in a way that spoils it. They are equivalents, not power creep, and nothing about them is balanced as an upgrade path.

Availability, honestly

Check your storeThe Chthonic Arsenal was promoted as the pre-order bonus, and post-launch some listings describe it as bundled with digital editions. That varies by storefront and changes over time. Look at the edition contents on the page you are buying from rather than trusting any guide, including this one.

Editions and what each adds are on the editions page.

Why the confusion exists

Bonus weapons are announced before the campaign arsenal is documented, so for months these were the only named guns in circulation. Sites building pages from launch-window material inherited that gap, and several published them as the main weapon list.

It is a good example of why this wiki labels the origin of every fact. The campaign arsenal is documented in editorial coverage of the released game; the bonus pack is documented in storefront and pre-order material. Both are real, and they are different lists.

Using them with weapon parts

Parts are conditional modifiers, and they care about how a gun is used rather than which gun it is. A multi-enemy blast part works on The Breakwater exactly as it works on the Field Surgeon.

The practical advice is unchanged: pick two guns, put your best parts on those two, and do not spread upgrades across nine weapons because you happen to own nine.

If the bonus weapons are missing

• Check the edition you actually own. Store libraries list edition contents.
• Restart after a purchase or upgrade so entitlements re-check.
• On Steam, verify the game files — the same step Frogwares recommends for crash troubleshooting also forces a content re-sync.
• They may unlock in-game rather than at the start. Check your weapon wheel after the first safe room.
