What Are Blackboxes in Subnautica 2?

Blackboxes are flight recorder capsules left behind by the colonists of the Cicada. Each one belongs to a specific colonist. Pick one up and NOA, your AI companion, plays back a postmortem recording of how that person died.

They are not optional collectibles. Recovering Blackboxes is how the story moves forward. NOA uses them to unlock new signals and point you toward new locations. In Survival Mode, the game sends you through them in a specific order.

The table above shows all 25 Blackboxes in the current Early Access build.

How to Find Each Blackbox

Anita

Anita has two Blackboxes.

Box 1 (160m North-Northeast of the Lifepod): Swim north-northeast from the Lifepod. Look for a large underwater tree with a bright pink flower. That is an Angel Comb Jelly. The Blackbox is on a platform beside it. Before you leave, interact with the flower. This unlocks the Digestion adaptation, which lets you eat local flora and sea creatures.

Box 2 (1,796m East of the Lifepod): Located 500m past the Alien Ruins. Dive deep into the chasm beneath the alien structures, down to around 379m below sea level. This is a late-game location.

Blackbox - Unknown

Found in an unnamed Cicada wreck 582m below the Lifepod, slightly southwest. This is one of the deepest Blackboxes in the early-accessible area. Prepare extra oxygen and supplies before diving.

Chap "Chap" Sovann

Chap has two Blackboxes.

Box 1 (221m Southeast of the Lifepod): Head southeast from the Lifepod. Look for a rocky crag with stone pillars. Find the tunnel opening and look for a hatch. Go inside and interact with the biobed. This gives you the Blackbox and an inventory slot upgrade. Scan the Repair Tool, Bioreactor, and a few more things while you're here.

Box 2 (387m North of the Lifepod): Located underneath the hole where you find the Mantis Blackbox inside the Old Habitat. Collect it on the same visit as the Mantis, Mogami, Quaker, and Wu boxes.

Chen "Eddy" Wei

Located 565m Southeast of the Lifepod inside an underwater cave. The cave entrance is South-Southeast of the heat-emitting coral. You will need the Heat Tolerance Adaptation to survive the temperature in this area.

E "Thing Two" Terbish

Located 392m North of the Lifepod, near Mogami's Blackbox inside the Old Habitat. Collect it on the same visit as the other Old Habitat boxes.

Iso

Located 1,782m East of the Lifepod inside the Cicada Wreck. This is a late-game location. You must repair the broken door to access the interior, then check the dining table for the Blackbox. Bring the Repair Tool.

Wander / K. "Wander" Wangmo

Wander has three Blackboxes.

Inside an underwater cave.

Box 2 Wander (245m South-Southwest of the Lifepod): Inside the hole beneath the Spider Dome. You'll need a Sonic Resonator here to blast the bloom.

Located east of the central heat-emitting coral between two stagged Mephits. Scan this plant as well if you haven't already.

Marc "Rowboat" Rho

Located 495m East-Southeast of the Lifepod inside an underwater cave. This cave cluster also contains the Gram, Eddy, and Zip boxes, so plan to collect all of them in a single run.

Mogami "Mogami" Kinu

Located 392m North of the Lifepod in the room before the Mantis Blackbox inside the Old Habitat. Collect it alongside the Mantis, Thing Two, Quaker, Wu, and Chap blackboxes during the same visit.

Phoebe "Gram" Grammaticas

Located 488m East-Southeast of the Lifepod inside the underwater cave, beneath the large central heat-emitting corals. This cave cluster also contains the Rowboat, Eddy, and Zip boxes.

Quaker

Located 390m North of the Lifepod in the room above the Mantis Blackbox inside the Old Habitat. NOA will not reveal this signal until you collect Tuba's Blackbox first. Equip the Oxygen Control biomod before entering. Most of the Old Habitat is flooded and oxygen runs low fast.

While here, scan the Sonic Resonator, both Battery Terminals, the Wakemaker Fragment, and the Scanner Station.

Ruby

Ruby has two Blackboxes.

Box 1 (403m North-Northeast of the Lifepod): Found between rocks shaped like a ribcage. Follow the NOA marker. A Tadpole transport fragment is nearby. Scan it before leaving.

Box 2 (1,420m East of the Lifepod): Inside the underwater cave beneath the Needler Nest. This is a mid-to-late game location. Watch out for Needlers in the area.

Sean "Sean" Harris

Located 453m Northwest of the Lifepod, deep within the Heat Biome. You'll find a small entryway that will lead you to an air pocket.

Singh

Singh has three Blackboxes.

Box 1 (213m North-Northeast of the Lifepod): On the sand near a platform under a small cliff. One of the earliest boxes you can find.

Box 2 (405m Southeast of the Lifepod): Inside a coral dome. Follow the NOA marker southeast from the Lifepod.

Box 3 (2,023m East of the Lifepod): Located 786m past the Alien Ruins inside the Cicada Wreck (Therapy Room). This is a late-game location.

Tuba

Located 238m North-Northeast of the Lifepod inside the last section of Camp One. Enter through the tube underground. While here, scan the Scanner Station, Wakemaker Fragment, and Power Cell Terminal.

Wu "Wu" Lianghai

Located 405m North of the Lifepod in the room before the Mogami Blackbox inside the Old Habitat. Collect it on the same visit as the other Old Habitat boxes.

Tziporah "Zip" Malk / Zip

Zip has two Blackboxes.

Box 1 (485m East-Southeast of the Lifepod): Deep inside the underwater cave beneath the central heat-emitting coral and sitting on an Angel Comb root.

Box 2 (2,092m East of the Lifepod): Lying on the seabed at the Metal Farms. This is a late-game location.

Zygimantis "Mantis" Tarvydas

Located 388m North of the Lifepod inside the Old Habitat. Found in the southeast room after climbing down from the Quaker Blackbox. Also scan the poster and the biobed while in this room.
