Quarantine Enforcement Platform

The Quarantine Enforcement Platform is a massive Alien weapon system that is located on the Mountain Island. It is the source of the energy beam responsible for causing both the Degasi and Aurora to crash on Planet 4546B, as well as destroying the Sunbeam during its rescue attempt.

The Quarantine Enforcement Platform was built by the Precursor Race around one thousand years ago, in order to contain the Kharaa Bacterium. Near one of the entrances an Alien Arch connecting to the Primary Containment Facility can be found.

The Player must locate a Purple Tablet to gain entrance to the Quarantine Enforcement Platform; several 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 the Kharaa Bacterium before being able to disable the Quarantine Enforcement Platform and leave the planet. If the player attempts to disable the facility before they cure themselves of the Kharaa Bacterium, they will be denied.

Warpers can be found patrolling in the waters around the Quarantine Enforcement Platform.

Three Ion Cubes can be found here.

Interior
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 Alien Tablet is required in order to unlock the upper entrance, the elevator, and the control 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. Two data terminals and two Ion Cubes 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
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 Cyclops submersibles. 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 Cube can be found here.

In the corner of the "ground floor" of the room is a winding hallway that leads to the Arch room, although it cannot be used until it's corresponding Master Alien Arch is activated in the Alien Thermal Plant. 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.

Audio
When the countdown for the Sunbeam's arrival ends, the player will receive one of two messages from their PDA, depending on their location:

Version 1
If the player is present at Mountain Island when the Sunbeam arrives, they will receive this message from their PDA:

Version 2
When the player is not present at Mountain Island during the arrival of the Sunbeam, they will receive this message from their PDA instead:

Power is routed via the attached terminal, allowing for the device to be deactivated if necessary. It is currently operating without parameters, suggesting it will target any ship within range.

Trivia

 * Previous names for the Quarantine Enforcement Platform were Precursor Gun, Precursor Global Defense System, Precursor Ground-to-Air Weapon System and the 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.
 * The three cube-like structures found around the Quarantine Enforcement Platform may be a variant of the Sonic Deterrents found near the Primary Containment Facility. Whether this was intention, or purely coincidence is unknown.
