Radio Store Apartment Safe Code – 1908

The first major safe you are likely to encounter is found in the apartment near the radio store during the opening section of the game.

Safe code: 1908

The combination is connected to the history of the nearby radio store. Exploring the apartment and shop gives you clues pointing toward the year the business opened. That year is 1908.

You can simply enter 1908 into the safe without completing the full clue trail if you only want the contents.

This is worth opening early, as resources are still fairly limited during the beginning of The Sinking City 2.

Redemption Church Watergate Code – 1672

While progressing through the flooded streets, you’ll eventually reach the Redemption Church and another watergate blocking your route.

Watergate code: 1672

The clues tell you that you need the year associated with the church bell. The church itself was built in 1667, while the bell was made and installed five years later.

That gives you:

1667 + 5 = 1672

Enter 1672 into the lock beside the watergate controls and you can continue your journey through the flooded city.

Devil’s Reef Hotel Room 301 Safe Code – 2137

There is another optional safe inside the Devil’s Reef Hotel. You’ll find it while exploring the upper floors of the building.

Room 301 safe code: 2137

On the third floor, look for the room hidden behind a movable cabinet. Push the cabinet out of the way and enter the room to find the safe.

The intended solution involves combining clues found around the hotel, including information connected to a set of lyrics and a safe-code note. If you’d rather skip the investigation, enter 2137.

Opening the safe rewards you with a pistol upgrade and ammunition, making this one particularly worthwhile if you’re exploring the hotel thoroughly.

Akeley Memorial Hospital Storage Code – 1308

During the Akeley Memorial Hospital section, you’ll eventually be able to access a locked Storage area in the basement.

Hospital Storage code: 1308

You’ll first need Anti-Rust Acid to get through the corroded outer door. Once you’re inside, you’ll find another locked gate protected by a four-digit combination.

The hospital contains several pieces of evidence that reveal the digits and their correct order. The final combination is:

1 – 3 – 0 – 8

Inside the locked area you’ll find a submachine gun upgrade along with additional supplies, so it’s worth making the detour before leaving the hospital.

Akeley Hospital Brain Puzzle Code – 13, 05, 36

The hospital also contains a strange numerical puzzle involving three brains and a machine in the Wireless Room.

Brain puzzle solution: 13 → 05 → 36

Unlike the standard four-digit safes, this puzzle requires three separate values.

Interact with each of the brains and collect their testimonies before checking your Investigation menu. The information they provide allows you to determine the three correct values.

Set them to:

• 13
• 05
• 36

Make sure you keep the zero in 05. Once all three values are correct, confirm the solution to complete the puzzle and receive Dream Essence.

Fishing Shop Symbol Lock Combination

Not every lock in The Sinking City 2 uses numbers. During the Fish Market section, you’ll find a locked container being held by a corpse inside one of the Fishing Shop lockers.

Correct symbol order:

Lighthouse → Rings/Rope → Star → Squid/Octopus

The exact appearance of the symbols is more important than their names, so look for the lighthouse first, followed by the coiled rope or rings, the star-shaped symbol and finally the squid or octopus.

Opening the container gives you a submachine gun upgrade.

Fish Market Locker Room Safe Code – 1496

Another optional safe can be found in the Locker Room within the Fish Market.

Locker Room safe code: 1496

You can reach the Locker Room after gaining access to more of the Fish Market and shutting off the steam blocking part of the Cutting Area.

There is a note beside the safe, although you may reach it before collecting everything needed to solve the investigation properly.

If you don’t want to come back later, enter:

1 – 4 – 9 – 6

The safe contains an upgrade for the Grenade Launcher. You may actually discover this upgrade before obtaining the Grenade Launcher itself, so don’t worry if you can’t equip it immediately.

Fish Market Salt Storage Combination – I, IV, IX, XVI

The Salt Storage door in the Cutting Area uses Roman numerals instead of a standard numerical keypad.

Salt Storage combination:

I → IV → IX → XVI

In regular numbers, that’s:

1 → 4 → 9 → 16

The combination is connected to the Sixteen Punishments investigation. Once you’ve collected the necessary clues, the correct sequence becomes clear in your Investigation menu.

Open the Salt Storage room and search inside for another Grenade Launcher upgrade. There’s also additional investigation content and Dream Essence to collect in the room, so don’t leave immediately after grabbing the upgrade.

Abandoned Office / Old Shop Safe Code – 6294

Later in the Fish Market chapter, you’ll encounter another safe during a sequence involving the Abandoned Office and Ma Fishface’s Shop.

Safe code: 6294

During the relevant memory sequence, interact with the ghostly figures around the area and listen to their conversations. Following the sequence eventually reveals the combination.

If you want to skip straight to the solution, enter:

6 – 2 – 9 – 4

The contents of this safe are important for continuing the sequence, including the Leyden Jar during the memory and the Heart of Stone when you return to the present.

Which Safe Codes Are Most Important?

If you’re only interested in progressing through the story, not every safe listed above is mandatory. Some are optional investigations designed to reward players who thoroughly explore Arkham.

However, the optional safes are still worth opening. Several contain weapon attachments that can noticeably improve your equipment, while other investigations reward Dream Essence that can be spent on Talents.

For a quick reference, the combinations to remember are:

• 1908 – Radio Store Apartment
• 1672 – Redemption Church watergate
• 2137 – Devil’s Reef Hotel
• 1308 – Akeley Hospital Storage
• 13 → 05 → 36 – Hospital Brain Puzzle
• Lighthouse → Rings/Rope → Star → Squid/Octopus – Fishing Shop container
• 1496 – Fish Market Locker Room
• I → IV → IX → XVI – Salt Storage
• 6294 – Abandoned Office / Old Shop

Do Safe Codes Change Between Playthroughs?

The combinations listed above apply to the current release version of The Sinking City 2. They are tied to the game’s environmental clues and investigations, so you can enter the correct solution directly even if you haven’t completed every clue associated with a particular safe.

If a future update changes any puzzle or combination, we’ll update this guide accordingly.
