AETHUS Facility Theta Open Gate: Perimeter Path and Entry

Opening the blocked main gate at Facility Theta requires circling around the exterior fence on the right side rather than forcing the jammed mechanism. Walking past where the perimeter barrier ends allows direct access into the biodome and automated laboratory.

Bypassing the Jammed Gate Mechanism

The front entrance of Facility Theta sits behind a reinforced perimeter gate overgrown with creeping fungal growth. Interacting with the gate subsystem terminal produces no mechanical response because invasive biological matter jams the motorized tracks.

The mechanism cannot be forced open with hand tools or standard mining lasers. You can circumvent the barrier entirely by following the exterior wall to the right. Follow the perimeter boundary around the building until the metal fence terminates against the rock wall. A clear gap exists past the end of the fence, allowing Maeve to squeeze into the outer courtyard without spending consumables or installing replacement servos.

An oxygen refill station stands immediately past the gap on the inner grounds. Monitoring suit air tanks remains necessary during the approach, as traveling through the Lost World quickly depletes standard reserves before upgrades are installed.

Retrieving Biolab Blueprints and Upgrades

Inside the primary structure, players encounter an automated bio lab station choked with phytotoxic residue. Although the machinery itself is damaged beyond repair, interacting with the console extracts both the manufacturing specifications for the Biology Lab outpost module and the operations program.

Examining the lab terminal and surrounding workbenches yields several critical schematics:

• Biology Lab: Allows the construction of biological synthesis equipment back at the surface settlement.
• Injector upgrades: Schematics for speed injectors and health injectors that improve operational efficiency underground.
• Herbicide Charge: A specialized chemical explosive designed to dissolve stubborn biological barriers blocking access to other installations, such as Facility Mu.

Proceeding deeper into the complex reveals an expansive biodome built around an enormous Greatwood tree. Data terminals inside this dome hold greenhouse habitat blueprints, which allow players to set up dedicated growing areas alongside a hydroponic bed at the surface base. The surrounding soil also contains native flora, including Mouldshroom colonies and Jaspite mineral nodes.

Overcoming High Spore Density in the Deep Bunker

Past the central biodome lies an inner bio-research bunker where suit filtration systems fail against heavy airborne contaminants. Entering this sector without biological protection rapidly drains Maeve's health due to dense clouds of pseudo-fungus spores.

Research logs left by the expedition describe staff incapacitation following accidental inhalation of these spores. The surviving data notes that native fauna carry natural resistance factors capable of stabilizing human respiratory tracts against the toxin.

Bypassing this environmental hazard requires constructing a Biology Lab at your outpost and compounding an Injector (Mycelial Antigen). Synthesizing this protective dose requires harvesting Mouldshroom specimens from the Theta perimeter, gathering Queen Mycelia from fungal nodes, and combining them with empty injectors manufactured from Tangrite bars and hardened glass. Once the antigen is active, exploration can proceed into the rear chambers to locate the terminal data drives and the personal keycard belonging to Ncuti Sinclair.

Theta Field Gear Decision Table

Preparing the correct inventory items before trekking to Facility Theta reduces backtracking to the surface hub and protects against lethal spore exposure.

Processing raw samples such as biomass and cultivating localized spores at your outpost ensures a steady supply of treatment injectors before you venture into the remaining locked research wings.
