UNLOCK // PDA CASE FILE
Can't Unlock the Moonpool in Below Zero
Below Zero uses a data-box route for the Moonpool, so following the original game's fragment locations sends you to the wrong place.
LAST CHECK
ANSWER LOCK // QUICK RESPONSE
Open the Moonpool data box at Koppa Mining Site, then build the module below water with the Habitat Builder. This is a data-box unlock in Below Zero, not the original game's two-fragment route.
SIGNAL CONFIRMEDBLUEPRINT DIAGNOSTIC // WHY IT ISN'T UNLOCKING
