The Shift+F12 menu in Kenshi is the game’s built-in level editor, a powerful but volatile tool that allows players to bypass the standard survival constraints to modify the world directly. Often referred to as the "modder's menu," it offers capabilities ranging from fixing broken pathfinding to creating entire custom settlements. Core Functionalities
The editor serves several distinct purposes for different types of players:
World Editing & Correction: Players primarily use the menu to fix physical glitches, such as moving a building that is clipping through terrain or deleting a misplaced object.
Creative Base Building: It allows for the placement of buildings and walls without the need for raw materials or labor. You can also use it to add interior layouts or exterior signs to existing structures.
Tactical "Cheating": Speedrunners and advanced players use it for teleportation by moving the camera in the editor, quick-saving, and then loading with "Reset Squad Positions" checked.
Pathfinding Repair: By laying down invisible "roads" or rebuilding the navmesh (paired with Ctrl+Shift+F11), players can resolve issues where characters get stuck or ignore walls. The Danger of the "Save" Button

The Shift + F12 menu in Kenshi serves as an in-game editor for fixing character collision issues, manipulating buildings, and altering the world environment [1]. Key tools include "Fix Stuff" for pathing errors and "Navmesh Tools" to ensure placed buildings are functional, though users should save before editing to avoid breaking game files [1]. kenshi shift f12 guide
In Kenshi, pressing Shift + F12 opens the In-Game Editor (also known as the Developer Mode or FCS Overlay). This is a powerful, albeit finicky, tool used for fixing bugs, repositioning buildings, and advanced base customization. Core Uses of the Shift + F12 Menu
The "Fix Stuff" Button: This is the most common use. If your characters are stuck in a wall, or a building pathing is broken, clicking "Fix Stuff" forces the game to recalculate navmeshes and local data. It can often resolve minor glitches without needing a full Import.
Repositioning Buildings: Unlike the standard build mode, the Shift + F12 editor allows you to move any structure—including those that are already completed. Click a building to see its transform gizmo. Use the Arrows to move it along the X, Y, and Z axes. Use the Circles to rotate it.
Pro Tip: This is the only way to perfectly align walls or fix "floating" buildings on uneven terrain.
Resetting Navmesh: If your characters are walking through walls or refusing to enter a door, use the "Navmesh Tools" section. Clicking "Regenerate" will rebuild the pathfinding grid for the local area.
Building Deletion: You can delete "ghost" buildings or misplaced structures that the normal dismantle tool won't touch. Simply select the object and press the Delete key on your keyboard. Key Controls & Navigation
W, A, S, D / Q, E: Moves the editor camera independently of your characters.
Town Placement: You can see the "Town Markers" (blue spheres). This shows the radius of your base. Moving this marker effectively moves your "territory," which dictates where you can build and where raids will trigger.
Buildings Menu: This allows you to spawn almost any asset in the game, including unique ancient ruins or decorative items not available in the standard research tree. Critical Warnings
Save Before Starting: The editor does not have an "Undo" button. One wrong click can delete a vital part of your base or a world-state object. This is the main reason people look this guide up
"Save Mod" vs. "Exit": When you are finished, do not just click "Save" unless you intend to create a new .mod file for the game. If you are just fixing a bug in your current save, perform your edits, click "Exit," and then save your game normally through the standard Esc menu.
World Objects: Avoid deleting or moving buildings in NPC towns (like the Hub or Blister Hill). This can break quest triggers, vendor spawns, and AI packages. When to use Shift + F12 vs. Importing
Use Shift + F12 for: Immediate physical fixes, like unsticking a character, rotating a misplaced turret, or fixing a gap in your walls.
Use Importing for: Major technical issues, resetting NPC populations, or clearing out world-level data corruption that the editor can't see.
Are you trying to fix a specific bug like a stuck character, or are you looking to use the editor for creative base building?
Here’s an informative guide to using Shift+F12 in Kenshi—the in-game editor that lets you modify the world, fix stuck characters, and even build your own towns.
While in-game (not on the main menu), press Shift+F12. A small window titled “Editor” will appear. You’ll also see a green wireframe overlay showing navmesh, zones, and objects. Don’t panic – you haven’t broken the game.
Important: Before doing anything, save your game manually. The editor overwrites data live. Reload if you mess up.
