Structural Analysis complete. Designation: super weapon. Evidence suggests this facility will intercept all ships attempting to approach or take off from the planet. Scanning for any method of disabling the weapon.

― PDA, Dialogue

The Precursor Array is a huge weapon that is located at the Mountain Island. It is the source of the energy beams responsible for causing both the Degasi and Aurora to crash on Planet 4546B, as well as eventually destroying the Sunbeam.

The weapon was built by the Precursor race around one thousand years ago, in order to prevent the spread of Carar.

The player must locate the purple Precursor Artifact to gain entrance to the facility; two of them are located on the Mountain, and a third is located inside near the barrier to the gun terminal. The player must cure himself of Carar before being able to disable the gun and leave the planet.

To view the weapon aiming and firing, type 'precursorgunaim' into the console and to view just the firing FX, type "playsunbeamfx" into the console. 

Warpers can be found around the Precursor Array.

A small amount of Ion Crystals can be found here.

Interior

The Precursor Array's interior consists of two major areas, the upper section and the submerged lower section. Both sections have separate entrances, although the player can take an anti-gravity elevator found within the facility in order to access one section from the other. The purple Precursor Artifact is required in order to unlock the upper entrance, the elevator, and the deactivation terminal room.

Upper Section

The entrance to the upper section can be found on the beach of the Mountain Island, a large door gives access to the interior from here. Multiple data terminals and Ion Crystals are found here. The gun itself, when on standby, is placed vertically as to not immediately alert the player to the fact that the facility is actually a super weapon, instead appearing as some kind of monument.

Lower Section

The entrance to the lower section is a large opening in the side of the "tower", which gives access to a large moonpool. The moonpool is just large enough to fit a Cyclops submarine. Inside the moonpool room are two doors, one leading to the right and one leading straight forward. The door to the right leads to the elevator, while the other door leads deeper into the facility, into a room dominated by a series of platforms and ramps.

In the corner of the "ground floor" of the room is a winding hallway that leads to the Precursor Teleporter room. Going up the ramps will lead the player to the control room. The deactivation terminal can be found here, which will unfold and activate when you are near it. After unsuccessfully using the terminal, the player will receive a notification from their PDA about the location of the Disease Research Facility.

Massive energy readings for this structure indicate it is the main reactor powering the alien weapon's laser system. If this system could be powered down, it may be possible to escape the planet's atmosphere.
