The Sinking City 2 Complete Map: All Locations, Areas, Safe Rooms, Items
Complete The Sinking City 2 map guide with all known areas, safe rooms, ERC Crates, key items, boss locations, weapon routes, and route checklist notes.
Use this The Sinking City 2 map guide as a route checklist for Arkham's flooded areas, safe rooms, key items, ERC Crates, bosses, weapons, and important return points. The sequel is not a single open-city map like the 2019 game. It is built around separate survival horror areas where you unlock shortcuts, solve room chains, return to safe rooms, and revisit earlier routes after finding new items.
Use the route anchors below for practical navigation: area map, safe room, key item, E.R.C. Crate, Activator Pen, shortcut, then boss or exit. Exact room labels can differ by guide wording, so this page uses confirmed location indexes and route anchors instead of invented coordinates.

Area Entry Points
These are the safest confirmed map entry points to use as route labels. Treat them as navigation anchors, not exact coordinate pins.
| Map Area | Use This Entry When | Related Route |
|---|---|---|
| Library Annex / Archive | You need the first area map, the Restricted Section route, Corentin, or the first E.R.C. Crate loop | Corentin route, E.R.C. Crates |
| Church / Redemption Church | You are blocked by investigation clues, floodgate progress, or occult symbol puzzles | Puzzle Solutions |
| Devil's Reef Hotel | You are following the Lorelei objective after the early investigation route | Story Walkthrough |
| Akeley Memorial Hospital | You need multi-floor routing, the Wireless Room Brain Puzzle, or hospital storage cleanup | Puzzle Solutions |
| Fish Market | You are solving Time and Tide, the Locked Buoy, Salt Storage, Locker Room safe, or statue route | Ezekiel Locked Buoy Puzzle, Safe Combination Solutions |
| Boss checkpoints | You are about to enter a heavy combat arena or scripted threat route | Shoggoth, Slither Prime |
Quick Answer
The Sinking City 2 map is a semi-open survival horror structure made of connected story areas rather than one freely explorable open world. Your route usually follows this loop:
- Enter a major area.
- Find the local map, safe room, and locked paths.
- Collect key items, notes, ammunition, and puzzle objects.
- Unlock shortcuts back to the safe room.
- Open ERC Crates when you have the E.R.C. Activator Pen or the needed route item.
- Save before boss rooms, flooded returns, and long backtracking routes.
The most important route anchors are the Library Annex, Church / Redemption Church, Devil's Reef Hotel, Akeley Memorial Hospital, Fish Market, exterior Arkham streets, safe rooms, E.R.C. Crates, Activator Pens, and boss arenas. If you are looking for one page to keep open while routing the game, start with the location table below and treat it as a map checklist.
Complete Map Overview
The Sinking City 2 uses haunted-house style level design. Each area has its own rooms, locked doors, shortcuts, resource loops, and enemy pressure. Instead of asking "where is the next district?", the better map question is "which item opens the next route, and how far am I from the nearest safe room?"
| Map Element | What It Means | Why It Matters |
|---|---|---|
| Major area | A story location such as the Library, Hotel, Hospital, or Fish Market | Main progression, bosses, and large puzzle chains |
| Safe room | Save, storage, crafting, and recovery point | Your reset point before dangerous routes |
| Shortcut | Door, ladder, side corridor, or flooded return route | Reduces backtracking and saves resources |
| Key item | Route object, puzzle piece, tool, or story item | Opens locked paths or finishes investigations |
| ERC Crate | Emergency Relief Crate with upgrade-style rewards | Often tied to weapon, inventory, or survival upgrades |
| Boss location | Arena or major threat room | Requires saving, ammo planning, and healing |
| Flooded route | Water-altered path or exterior crossing | Changes enemy pressure and visibility |
All Locations and Areas
This table keeps the major areas in one place. Some route order can vary by objective progress, so use the "Map checklist" column instead of treating it as a hard coordinate list.
| Location / Area | Route Role | Map Checklist | Notes to Verify |
|---|---|---|---|
| Arkham exterior streets | Connector and atmosphere route | Watch for flooded paths, ambush corners, and return shortcuts | Use nearest dock, safe room, and objective name as anchors |
| Library Annex / Archive route | Early story and investigation hub | Find the area map, mark the first E.R.C. Crate, continue through the Restricted Section, and return after the Corentin Activator Pen | The first crate loop is tied to the Corentin route |
| Corentin room / meeting route | Named-character story route | Restricted Section -> Ritual Book -> move cabinet -> upstairs room -> Corentin | Pick up the E.R.C. Activator Pen and User Manual after the scene |
| Devil's Reef Hotel | Major story destination | Track Lorelei objective, check guest rooms, unlock shortcuts, and save before long interior pushes | Pair with the gas puzzle and Lorelei route |
| Akeley Memorial Hospital | Major multi-floor horror area | Prioritize local map, safe room, face/puzzle chain, locked wards, and shortcut returns | Often treated as one of the standout maps; exact floor labels should be confirmed |
| Fish Market | Later-game combat and route area | Enter stocked, mark exits, expect heavier enemy pressure, and save before wave-style encounters | Pair with weapon, E.R.C., and inventory-expansion cleanup |
| Abandoned Firehouse | Early resource and route area | Clear side rooms before leaving and note any locked paths | Listed as an early-game area in existing site coverage, but exact route order needs confirmation |
| Church / investigation area | Puzzle route | Track notes, clue links, and locked investigation steps | Mentioned by walkthrough coverage before the Devil's Reef Hotel route |
| Boss arenas | Combat checkpoints | Save, craft, reload, and enter only after checking healing and ammo | Boss names and exact arenas should be cross-linked as pages are expanded |
Safe Rooms
Safe rooms are the backbone of The Sinking City 2 map route. Every time you find one, treat it as a new planning base rather than just a save point.
| Safe Room Use | What to Do |
|---|---|
| First visit | Save immediately, check storage, and note the nearest locked doors |
| Before a boss | Craft ammunition, reload all equipped weapons, and keep at least one healing item |
| Before a flooded route | Check Night Shade, healing, and whether you have enough ammo to return |
| After finding a key item | Save before backtracking in case the return route spawns new enemies |
| Before spending talent points | Upgrade the problem you are actually facing: reload speed, weapon handling, health, or inventory |
Route notes:
- Safe rooms are marked by recognizable safe-room symbols and save equipment.
- The first safe room teaches the save, storage, and crafting loop.
- Later safe rooms should be used as route hubs for E.R.C. Crates, boss preparation, and item cleanup.
For survival planning, pair this page with the Talent Points guide and Night Shade guide.
Key Items and Route Objects
Key items matter because The Sinking City 2 map is built around lock-and-key progression. Do not leave a major area until you have checked whether a new item opens an earlier door, crate, side room, or shortcut.
| Key Item / Object | Where It Fits | Route Use |
|---|---|---|
| Local area map | Early in a major location | Reveals room structure and helps mark return points |
| E.R.C. Activator Pen | First major pickup is near Corentin after the Library Annex scene | Opens Emergency Relief Crates after you return to marked crates |
| Puzzle notes and documents | Investigation rooms, desks, corpses, side rooms | Provide solutions, clue links, and route hints |
| Story objective items | Main route areas such as Hotel, Hospital, and Fish Market | Advance the story and often change return routes |
| Weapon parts / accessories | ERC Crates and optional exploration routes | Improve combat consistency and reduce ammo waste |
| Night Ore / Night Shade resources | Survival route pickups | Support revival and longer pushes away from safe rooms |
For late-game cleanup, write down the room name, nearest safe room, and locked path that each key item affects.
ERC Crates
ERC Crates are some of the highest-value map objects because they can reward inventory, weapon, or survival upgrades. If you see a white or gold upgrade-style crate, mark it even if you cannot open it yet.
| ERC Route Step | Checklist |
|---|---|
| Find the crate | Record the room, hallway, floor, and nearest safe room |
| Check the lock | If it requires the activator pen, leave it marked for return |
| Find the E.R.C. Activator Pen | The first major pen is after the Corentin route near the safe-room door and user manual |
| Return to earlier crates | Start with the archive hallway crate noted before the deeper library route |
| Spend the reward wisely | Prioritize inventory, handgun reliability, or the weapon upgrade you actually use |
Route notes:
- The Library Annex route has an early E.R.C. Crate before you have the first pen.
- The E.R.C. Activator Pen appears after the Corentin conversation route, near safe-room materials.
- E.R.C. rewards can include weapon accessories, inventory expansion, Dream Essence, ammo, or upgrade-style progression items.
For all 13 crate tracking, use the E.R.C. Crates guide.
Weapon and Important Item Locations
The safest way to cover weapon locations right now is to route by item type and area role, not by unverified exact coordinates. Use this as an item-location checklist while the full map is still being verified.
| Item Type | Best Place to Check | Route Priority |
|---|---|---|
| Handgun ammo | Small side rooms, early safe-room routes, desks, cabinets | High: keeps basic enemies manageable |
| Weapon accessories | ERC Crates and optional locked routes | High: can improve ammo efficiency |
| Bonus weapons | Inventory, storage, edition reward checks | Depends on edition ownership |
| Shotgun-style emergency weapon | Major combat areas and weapon progression routes | High before tight corridors and boss rooms |
| Explosives / heavy ammo | Boss preparation routes and late-game resource rooms | Save for bosses and groups |
| Healing items | Safe rooms, medical rooms, side cabinets | High before leaving a safe route |
| Puzzle objects | Desks, bodies, locked rooms, investigation scenes | Required for route progression |
| Area maps | Early rooms or wall boards near route entrances | High: reduces missed doors and return trips |
If you are trying to find all weapons, check the weapons guide after every major map transition and before every boss.
Boss Locations
Bosses should be treated as map checkpoints. Even when the exact room name changes by route language or patch, the preparation pattern stays the same: find the nearest safe room, craft, reload, then enter the arena.
| Boss / Threat Page | Likely Map Role | Preparation Checklist |
|---|---|---|
| Shoggoth | Heavy mythos boss encounter | Save, carry burst damage, keep healing, learn the attack window before spending heavy ammo |
| Slither Prime | Major Slither-style threat | Reload before entry, conserve precision ammo, avoid wasting shots into bad angles |
| Fish Market wave threats | Later-game pressure route | Bring crowd-control options and keep a retreat path in mind |
| Hospital ambush threats | Multi-floor corridor pressure | Clear rooms slowly and avoid overcommitting far from the safe room |
Boss route notes:
- Treat boss rooms as save-and-loadout checkpoints.
- Link each boss to the nearest safe room as you complete cleanup passes.
- Use boss names as preparation anchors when exact room labels differ across walkthroughs.
Corentin Location
Players searching for Corentin location should start with the Library Annex route. Follow the Restricted Section, take the Ritual Book, move the cabinet that blocks the exit, continue upstairs, and enter Corentin's room. After the scene, pick up the E.R.C. Activator Pen and E.R.C. User Manual nearby before leaving.
For the dedicated character page, see Corentin in The Sinking City 2.
Map Route Tips
The best map strategy is to think in loops: safe room, locked path, key item, shortcut, return. That pattern keeps you from wasting ammunition while wandering.
| Situation | Best Route Habit |
|---|---|
| You enter a new area | Find the map and safe room before pushing deep |
| You see a locked door | Write down the room name and nearby landmark |
| You find an ERC Crate | Mark it even if you cannot open it yet |
| You pick up a key item | Backtrack through earlier locked paths before leaving the area |
| You reach a flooded exterior route | Move slowly, conserve ammo, and identify the return path |
| You are low on ammo | Retreat to the safe room instead of forcing a new room |
| You hear or trigger a major enemy | Do not spend heavy ammo until you understand the attack pattern |
| You finish a boss | Return through nearby rooms for missed items before advancing |
Flooded Routes and Backtracking
Flood water changes how you read the map. It can reduce visibility, make exterior traversal more dangerous, and alter which routes feel safe on return. When the story pushes water levels higher, do a second pass through old map notes:
- Which shortcut still works?
- Which locked door did you skip?
- Which ERC Crate did you mark but leave unopened?
- Which safe room is closest to your next objective?
- Which boss or heavy enemy route requires extra ammo?
The Sinking City 2 map rewards players who keep simple notes. You do not need perfect coordinates; you need reliable anchors: safe room, locked door, item, shortcut, boss.
FAQ
Is The Sinking City 2 map open world?
No. The Sinking City 2 is closer to semi-open survival horror than a single open world. It uses separate areas with locked paths, shortcuts, puzzles, safe rooms, and backtracking.
What are the main areas in The Sinking City 2?
Major areas include Arkham exterior streets, the Library Annex route, Church / Redemption Church, Devil's Reef Hotel, Akeley Memorial Hospital, Fish Market, and other story locations such as the Firehouse.
Where is the map in The Sinking City 2?
Area maps are usually found near early route rooms, wall boards, or side rooms before deeper progression. The library/archive route notes mention a map near the archive hallway before an ERC Crate.
Where are safe rooms in The Sinking City 2?
Safe rooms appear throughout major areas and act as save, storage, and crafting hubs. Because exact room names can vary by route and patch, mark every safe room by its nearest landmark and use it as your base for backtracking.
Where are ERC Crates located?
E.R.C. Crates appear in optional and side-route positions. The full route has 13 crates and 13 Activator Pens. The first crate loop is in the Library Annex: mark the crate, meet Corentin, pick up the first Activator Pen, then return to open it.
Where is Corentin located?
Corentin is on the second floor of the Miskatonic Library Annex after the Restricted Section and Ritual Book route. Pick up the E.R.C. Activator Pen near him before leaving.
Where are the weapons in The Sinking City 2?
Weapons and weapon upgrades are tied to safe-room progression, ERC Crates, optional exploration, and edition rewards. For now, route by item type: check side rooms for ammo, ERC Crates for accessories, and safe-room/storage systems for bonus weapons.
Does the map change as the story progresses?
Yes. Flooded routes and story progress can change how areas are navigated. Recheck old locked doors, marked crates, and shortcut paths after major story objectives.
What should I do before leaving a map area?
Save, open available shortcuts, check ERC Crates, spend useful upgrades, collect local documents, and revisit locked doors affected by your newest key item. Leaving an area with unopened route loops usually costs more time later.
