"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 Quarantine Enforcement Platform (QEP) is a massive Precursor weapon system that is located on 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 the Carar bacterium from Planet 4546B to other planets.

The player must locate the purple Precursor Artifact to gain entrance to the facility; seven of them are located on the island, one of them located inside the facility itself on the balcony near the barrier to the control room, and one is located in an underwater cave near the base. The player must cure himself of Carar before being able to disable the facility and leave the planet. If the player attempts to disable the facility before they cure themselves of Carar, they will be denied.

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 patrolling in the waters around the Quarantine Enforcement Platform.

A small number of Ion Crystals can be found here.

Interior Edit

The Quarantine Enforcement Platform's interior consists of two major areas, the upper 'engineering' 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 control room.

Upper Section Edit

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. Two data terminals and two Ion Crystals are found in the upper section. The Quarantine Enforcement Platform itself, when on standby, is placed vertically as to not immediately alert the player to the fact that it is actually a super weapon, instead appearing as some kind of tower-like monument.

Lower Section Edit

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 large enough to fit two or three Cyclops submarines. 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. Another Ion Crystal can be found here.

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 the player is 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 facility.

Trivia Edit

  • Previous names for the Quarantine Enforcement Platform include Precursor Gun, Precursor Global Defense System, Precursor Ground-to-Air Weapon System, and Precursor Array.
  • Previous versions of the weapon were positioned in a way where it was more apparent that it was in fact a weapon system. The current version makes this less obvious by having the weapon point straight up prior to firing, appearing like a tower.
