Building the perfect underwater base in Subnautica 2 is hard enough already, but a lot of players are hitting the same weird roadblock: the Sign blueprint just refuses to appear.
Naturally, most people try scanning the signs scattered around the starting area. The problem is… that doesn’t seem to work at all.
After plenty of Reddit digging, community testing, and early-access exploration, players now think they’ve figured out how the Subnautica 2 Sign blueprint actually unlocks — and it’s much easier to miss than you’d expect.
Here’s the current best method for getting Signs unlocked in Subnautica 2, including Wall Rack fragment locations, possible blueprint bugs, and what you should scan first.
How to Get the Sign Blueprint in Subnautica 2
Right now, the strongest community evidence suggests the Subnautica 2 Sign blueprint is connected to the Wall Rack or Wall Anchor research chain.
In other words:
- There doesn’t appear to be a standalone Sign fragment
- Scanning existing Signs does not unlock the blueprint
- Most players unlocked Signs after scanning Wall Rack-related fragments
Several players reported getting the Sign blueprint immediately after researching the Wall Rack, while others believe the trigger comes specifically from the Wall Anchor.
So if you’re searching for the Subnautica 2 Sign blueprint location, your main goal should be finding and scanning Wall Rack fragments first.
Subnautica 2 Wall Rack Fragment Locations
If the Sign blueprint still hasn’t unlocked, these are the known Wall Rack fragment locations discovered by the community so far.
Northeast of the Lifepod
One Wall Rack fragment can reportedly be found northeast of the starting Lifepod area.
Coordinates:
-320595, 420914, -2273
This is one of the earliest possible scans tied to the Sign blueprint unlock.
North of the Starting Area
Another fragment has been discovered roughly along a 15° heading from the Lifepod.
Coordinates:
-330580, 412969, 3666
Players exploring this region for base-building blueprints often find this one naturally.
Near the NOA Doorway Region
A third Wall Rack fragment has been found near the NOA doorway area, sitting on top of a box close to the aggressive “headbutting fish” zone.
Coordinates:
-337802, 396331, -445
This seems to be the fragment most players accidentally miss during normal progression.
Why the Sign Blueprint Is So Confusing
The biggest issue right now is that Subnautica 2 never properly explains how Signs unlock.
Most players naturally assume:
- Signs should unlock from scanning Signs
- There should be a dedicated Sign fragment
- The blueprint is tied to story progression
But current community testing suggests none of those are true.
Instead, the Sign blueprint appears to be hidden behind unrelated interior decoration research, which is why so many players finish large parts of the game without ever unlocking it.
Can You Unlock Signs Before the Hot Zone?
Yes.
Multiple players confirmed they unlocked the Subnautica 2 Sign blueprint before entering the Hot Zone, meaning this is not a late-game blueprint.
If you’ve already reached deeper areas without Signs unlocked, there’s a good chance you simply missed one of the Wall Rack scans earlier in the game.
Is the Sign Blueprint Bugged in Subnautica 2?
Possibly.
Since Subnautica 2 is still in early access, some players believe the Sign blueprint occasionally fails to unlock correctly even after scanning the required fragments.
If the blueprint still won’t appear, players recommend trying:
- Reloading your save
- Restarting the game
- Building another base piece
- Returning to rescan fragments later
- Crafting additional interior modules
A few players reported the blueprint appearing later after returning to their base, so there may be delayed unlock behavior in the current build.
Final Answer
If you can’t find the Sign blueprint in Subnautica 2, don’t waste time scanning the pre-placed Signs in the starter area. Based on current community discoveries, the blueprint is most likely tied to the Wall Rack or Wall Anchor research chain instead.
To unlock Signs, focus on scanning every Wall Rack fragment location you encounter before entering the Hot Zone. Right now, that’s the most reliable method players have found for getting the Sign blueprint unlocked in Subnautica 2.
