Direct answer
Backpack is a real Solarpunk inventory feature, but it has already gone through launch-week bug fixes and temporary disabling. If you are looking for the old upgrade spot, do not trust older videos blindly — check the current patch notes first.
Current Backpack status
The live-build story around Backpack is simple:
- players immediately noticed Backpack inventory pagination and wanted a cleaner UI
- the developer later said backpacks were temporarily disabled after causing major problems
- the official update notes then said a backpack issue affecting multiplayer clients was fixed
- inventories corrupted by that bug received a repair function
That means Backpack is best treated as a moving target rather than a stable evergreen guide page.
What players actually want to know
Most Backpack searches are really asking one of these things:
- where the upgrade is
- whether it is working in the current build
- why the inventory feels split or paginated
- what to do after the backpack bug breaks machine or chest interaction
If your main problem is simply storage pressure, use the current resource and progression pages first instead of chasing an old location clip.
Quick checks
If Backpack is not behaving as expected:
- check the latest Steam announcements for the newest fix list
- compare the date of the video you found with your current build
- if inventory broke after pickup, look for the repair behavior mentioned in the official notes
- do not assume the same location still applies after a bug fix patch
- if the issue is only storage pressure, switch to planning your next resource unlock instead of detouring for a stale upgrade route
Why this page stays conservative
The safest answer is the one that matches the live build you are actually on. Backpack guides are only useful when they match your version, so this page focuses on the current status and the most reliable next step instead of pretending every old location clip is still valid.
