The Sinking City 2 Achievements Guide
The Sinking City 2 has 23 achievements worth a total of 1,000 Gamerscore, and although several unlock automatically through the story, completing the full list requires much more than reaching the ending. You also need to solve eight optional investigations, obtain four weapons, unlock every Talent, defeat specific enemies, finish two collectible sets within a single playthrough, and continue into New Game+.
The biggest completion risk is overlooking Emergency Relief Crates or Mushroom Jack broadcasts, since both related achievements require their entire collection to be completed during one playthrough. This guide therefore starts with the tasks that should remain active throughout the game before covering story achievements, puzzle solutions, weapon locations, combat requirements, and the final New Game+ cleanup. Progression details and late-game locations are included below, so some achievement spoilers are unavoidable.

Best Route To Unlock Every Achievement
The safest route to all 23 achievements is to collect every Emergency Relief Crate and listen to every Mushroom Jack broadcast as you progress, complete each optional investigation when you reach its location, pick up all four weapons, unlock every Talent, and then collect the new Ex Oblivione writings in New Game+.
Five achievements are connected directly to major story milestones, so those should unlock naturally while completing Parts 1 through 9. The optional puzzle achievements are also arranged throughout the story, beginning with the Apartment 5 wall safe in Part 1 and ending with two investigations at the Fish Market during Parts 8-2 and 8-3.
Weapon pickups begin with the Shotgun in Part 4, followed by the Submachine Gun in Part 6, Rifle in Part 7-2, and Grenade Launcher in Part 8-2. The Hospital also contains the three Nightmare enemies required for Sterilizer, making Parts 7-2 and 7-3 particularly important for achievement cleanup.
From Oblivion is the only achievement tied specifically to the Ex Oblivione New Game+ content. After unlocking it and completing every other requirement, For Her should serve as the final completion achievement.
Achievements To Track From The Start
These achievements are better treated as playthrough-wide goals rather than something to clean up at the end. Emergency Relief Crates and Mushroom Jack broadcasts must each be completed within one playthrough, while the Talent achievement requires every option at the Talent Table.
Behind Every Crate Man...
Unlock every Emergency Relief Crate in a single playthrough to earn Behind Every Crate Man.... DLC crates are excluded from the requirement, but every crate counted as part of the main game must be found and opened before finishing that playthrough.
Mycophile
Listen to every Mushroom Jack broadcast during one playthrough to unlock Mycophile. Finding a broadcast is not enough by itself; interact with it and listen so it counts toward the achievement before moving on.
What Dreams Are Made Of
Unlock every Talent at the Talent Table found in Safe Rooms to earn What Dreams Are Made Of. Continue purchasing Talents throughout the game instead of leaving the entire requirement until the final sections.
All Story Achievements
The five story achievements follow the main progression from Miskatonic University through the Badlands. None of their listed requirements involve a separate collectible set or optional code, so they should unlock as you complete the associated story events.
Welcome To Arkham!
Reach the Miskatonic University Library at the end of Part 1 to unlock Welcome To Arkham!. The achievement is tied to arriving at the university rather than one of the optional investigations available during the opening section.
Soulmates
Perform the ritual during Part 6 to unlock Soulmates. This occurs after bringing Lorelei to Correntin, with the achievement awarded following the resulting cutscene.
Bodysnatchers
Escape Akeley Memorial and return to the boat during Part 7-3 to unlock Bodysnatchers. The achievement does not trigger immediately after every Hospital objective is completed, so continue until you have left the building and reached the boat.
Bigger Fish To Fry
Survive the Arkham Fish Market and leave the area during Part 8-3 to earn Bigger Fish To Fry. The achievement is connected to completing the Fish Market story sequence rather than either of its optional investigation puzzles.
Timeless Dawn
Defeat the Slither Prime in the Badlands during Part 9 to unlock Timeless Dawn. This is the final listed story achievement before the separate New Game+ requirement.
All Puzzle Achievements And Solutions
There are eight investigation achievements connected to optional safes, machines, mysteries, and locked areas. They begin as early as Part 1 and continue through the Fish Market, so handling them in story order reduces the chance of leaving one behind.
The Inheritance
Investigate the wall safe inside Apartment 5 during Part 1. Enter 1908 as the safe code and open it to complete the investigation and unlock The Inheritance.
The Other Gods
Complete the church mystery during Part 3 by charging the Trident in the church loft and placing the ceremonial dagger into the altar. After those steps, defeat the monster in the lower level to finish the investigation and unlock The Other Gods.
The Red Press
Investigate the cursed press at the Printing House during Part 5. Find all three printing plates, place them into the printing press, and flip the pieces until every one of them is gold to unlock The Red Press.
The Siren's Call
Open the safe in Room 301 during Part 6 to complete the alluring-song investigation. The solution is taken from the Safe Code Letter and the Baby, One More Tide lyrics clue, but you can enter 2-1-3-7 directly to unlock The Siren's Call.
The Whisperers
Solve the machine connected to the brains inside the Hospital's Wireless Room during Part 7-2. Set Primary to 13, Secondary to 5, and Tertiary to 36 to complete the brain puzzle and unlock The Whisperers.
The Vault
Open the locked Storage connected to the Hospital Morgue during Part 7-3. Enter 1-3-0-8 as the code to finish the investigation and unlock The Vault.
The Damned
Investigate the sixteen punishments at the Fish Market during Part 8-2. Open the Salt Storage by entering I, IV, IX, and XVI in that order, then break the Dream Essence body inside to complete the investigation and unlock The Damned.
The Drowned
Find the Ezekiel buoy locker inside the Fish Market's Fishing Shop during Part 8-3. Set the symbols to Lighthouse, Rope, Starfish, and Octopus to open the mysterious locker and unlock The Drowned.
Weapon And Combat Achievements
Four achievements are awarded for obtaining weapons found in specific story areas, while Sterilizer requires defeating three Nightmare enemies spread across the Hospital. These are not the same as the automatic story milestones, so search their listed rooms before leaving each major location.
Out Of Your Shell
Obtain the Shotgun during Part 4 to unlock Out Of Your Shell. At the whale blockage, travel through the Safe Room and go behind the bar, where the Shotgun can be found inside its case.
Fast Friends
Obtain the Submachine Gun during Part 6 to unlock Fast Friends. The weapon is located in the basement of the Hotel near the ventilator.
We Aim To Please
Obtain the Rifle during Part 7-2 to unlock We Aim To Please. Find it through the mirror door inside the Hospital's Prosthetics Workshop.
Sterilizer
Defeat all three Nightmare monsters associated with the Hospital to unlock Sterilizer. One is found in the Upper Yard, another is in the Maintenance Room, and the final Nightmare appears in the Restricted Area after leaving the Hospital.
A Blast From The Past
Obtain the Grenade Launcher during Part 8-2 to unlock A Blast From The Past. The weapon is behind the double Starfish door located off the Fish Market's Market Hall.
New Game+ And Completion Achievements
The final two achievements sit outside the normal story and investigation route. From Oblivion requires the Ex Oblivione New Game+ content, while For Her is awarded only after every other achievement has been completed.
From Oblivion
Enter Ex Oblivione in New Game+ and collect all of the new documents that were not present before. Reading every one of these new writings unlocks From Oblivion.
For Her
Unlock the other 22 achievements to earn For Her. If it remains locked, check the one-playthrough collectible requirements, the eight optional investigations, all four weapon pickups, the three Hospital Nightmares, every Talent, and the Ex Oblivione writings.
Final Blurb
Most of The Sinking City 2's achievements fit naturally into the game's progression, but a complete run depends on consistently checking optional areas rather than rushing from one story milestone to the next. The puzzle achievements are spread across Parts 1 through 8-3, the weapon pickups begin in Part 4, and both collectible sets must be finished within a single playthrough.
Keep the Emergency Relief Crates and Mushroom Jack broadcasts active as long-term priorities, finish every investigation when its location becomes available, and thoroughly search the Hotel, Hospital, and Fish Market for their weapons and combat requirements. Once the main-game list is complete, the Ex Oblivione writings in New Game+ provide the final step before For Her unlocks.
