Where Are Besiege Saves and Machines Stored?
Besiege Spiderling Studios LocalLow folder with machines, saves and settings on PC.
Last updated
Besiege is a Unity game, so machines, campaign progress and settings live in LocalLow under Spiderling Studios. Machines save as .bsg files you can trade like baseball cards.
The multiverse update reorganized parts of the tree, so ancient guides mislead. Copy the whole Besiege folder and machines plus progress travel together.
Where Besiege stores this, by platform
%USERPROFILE%\AppData\LocalLow\Spiderling Studios\Besiege
Machines are .bsg files in the machines area with saves and settings nearby. Exact inner names shifted across updates, so back up the full Besiege folder with the game closed.
Frequently asked questions
How do I share a Besiege machine?
Send the .bsg file and have them drop it into their machines folder. Both players need matching game versions for complex builds.
How do I back up Besiege progress?
Copy the entire Besiege folder from LocalLow\Spiderling Studios. That covers campaign saves, machines and settings.
