Blue Tablet

The Blue Tablet can be found in the Alien Thermal Plant, 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.

Trivia

 * The data bank entry notes that the alien character on the tablet resembles an upper-case “H”.
 * The Blue Tablet used to require one Ion Cube and two Diamonds.
 * At one point it was not possible to drop the Alien Tablets to scan them, and just picking up the Blue Tablet would not unlock the Blueprint.  Making it possible to accidentally render the Blue Tablet uncraftable.
