There are a handful of Parallel Processing Units you need to find in order to progress the story in Subnautica: Below Zero. In this guide, we will go through all Subnautica: Below Zero Parallel Processing Unit Locations.
Subnautica: Below Zero Parallel Processing Unit Locations
The units you can are looking for can be crafted if you manage to gather some materials. In total, there are three fragments scattered across different locations in Mercury II. If you don’t know what that is, Mercury II is actually a sunken ship underwater.
The ship is in many parts found in the Purple Vents and Lilypad Islands biomes if you go east of Delta Island. Each part of the ship you find will have at least one Parallel Processing Unit.
The best way to find them is by using a Laser Cutter. If you don’t have one, you can craft it with 1x battery, 1x Crystalline Sulfur, 1x Titanium, 2x diamonds. Search every nook and cranny of the Mercury II wreckage and scan the fragments.
You can craft the Parallel Processing Unit after scanning the fragments. Use the Fabricator to craft it. You would also need to craft Test Override Module with 1x Parallel Processing Unit, 1x copper wire, 1x titanium, and 1x lead.
When you craft the Test Override Module head back to the Delta Station. Reach the radar tower at the summit. Put the module inside the panel before going back down to deactivate the radar.
And that’s everything you need to know about Subnautica: Below Zero Parallel Processing Unit fragments.
