Alien Tablets (Disambiguation)

Read at own risk This article contains unmarked spoilers. Players new to the game would want to avoid or be cautious toward this article.

Alien Tablets are items required to disable various Forcefield Controls in Alien Bases and other alien structures.

The Alien Tablets are flat metal-like objects featuring various holes and attachments on the outer edges, with a large alien symbol visible in the middle of the object.

How the devices were used by the Precursors is unknown. The Data Bank Entry for the Blue Tablet suggests that as well as granting security clearance, they may have functioned as personal computer of a sort, possibly similar to a PDA. It is known that the Precursors possessed a form of telepathy that allowed them to interface with their technology in ways that we are unable to.

Commonly found with the Alien Tablet is the ion crystal, which is needed for fabrication of the ion battery and ion power cell.

Purple Tablet

The Purple Tablet is usually the first Alien Tablet to be found, and is very frequently used in a number of locations. There are currently eight found in the game. The Quarantine Enforcement Platform requires three to unlock the upper entrance, the anti-gravity elevator, and the control room. The three Purple Tablets needed to unlock these doors can be found onsite; four on Mountain Island, and one inside the facility in the room before the deactivation terminal. A sixth can be found in the Degasi Seabase on the Floating Island, which could have possibly been found by Bart Torgal following his return to the island. The rest can be found in the Mountain Island's Caves. After scanning the broken Purple Tablet in front of the Quarantine Enforcement Platform's land entrance, the player can craft Purple Tablets at the Fabricator using an Ion Cube and two Diamonds.

Purple Tablets are described in a Degasi Seabase PDA recording as being nearly indestructible.

The Purple Tablet can be used optionally to access the four Sanctuary Caches. It is also used to unlock certain doors in the Alien Thermal Plant and Disease Research Facility.

The Alien writing on the artifact strongly resembles a "U".

Recipe

Data Bank Entry

This carbon-based device is lighter than it looks, and features a symbol which resembles a 'U', lit up in purple. Despite the onboard power still functioning, algae growth on the exterior indicates it was abandoned hundreds, perhaps thousands of years ago. While the technology is far beyond federation levels, and there is no obvious way to interface with it, it should nonetheless be possible to fabricate a precise physical copy of the device, if necessary.

Orange Tablet

The Orange Tablet is the rarest Alien Tablet in Subnautica, and can be found in the Deep Grand Reef Degasi Seabase on a desk, and is presumed to be what Marguerit Maida had discovered, as shown in this log. This Alien Tablet is exclusively used to access the Lost River Laboratory Cache. The Orange Tablet is craftable, but only one terminal requires the artifact.

The Alien Writing On the artifact resembles  "N".

Data Bank Entry

This device hums slightly, and displays an orange-lit symbol resembling an 'n'.

Blue Tablet

The Blue Tablet can be found in the Precursor Thermal Power Generator, and is used to access the Primary Containment Facility. One Blue Tablet is needed to gain entrance to the facility, and a second one is used to unlock the Moonpool room. However, only one Blue Tablet is available for pickup from the Alien Thermal Plant. It is craftable after the player either picks this Blue Tablet up, or scans it.

Blue Tablet: precursorkey_blue 

Recipe

Data Bank Entry

Smooth and cold, with a blue light which illuminates an alien symbol resembling an upper case 'H'. While it is likely these devices served in part as security clearance for whoever constructed them, their size suggests some additional purpose, such as personal computers. Whatever the case, the technology is far beyond humanity's own.
