How to get the Bioscanner in Subnautica 2
The Bioscanner is a late-game upgrade to the standard Scanner in Subnautica 2 that allows players to scan marine creatures and unlock additional Biomods. According to PC Gamer, this upgrade is an important addition to the player’s toolkit and should be obtained as early as possible, as creature scan data is not retroactive—players who have already encountered and catalogued creatures without the Bioscanner will need to locate and re-scan them with the new tool to collect the associated Biomods.
To acquire the Bioscanner, players must first progress to the Alien Ruins area, which becomes accessible after completing objectives at the Tadpole Pens and traversing a large open ocean section. The guide recommends equipping the Tadpole with a Depth Module before exploring this region, as the Alien Ruins exist in deep waters where pressure from the ocean depths poses a significant threat to unprepared vessels.
