Operation Subterra

Strike Silent Valley Mine, confirm uranium with a portable near-infrared spectrometer, push into Chem-Extraction to verify and secure yellowcake, interrogate for the Maunga Nui Port container number, then seize the shipment before exfil and gear decon at Erewhon.

Maunga Nui Port shipment intercept

Scott Davis, the turned Sentinel commander captured at Skell Security R&D Center, reports uranium deposits at Silent Valley Mine and yellowcake production at the Chem-Extraction Complex for black-market resale.

A shipment is staged to leave through Maunga Nui Port. Even if the material is not weapons-grade, it is a step toward dirty-bomb supply chains and the entire pipeline must be shut down.

Clear Silent Valley Mine, confirm uranium, call in a security team, then move to Chem-Extraction, mask up before entering, inspect barrels, and interrogate the high-ranking commander for shipping-container PID before the port intercept.

  • MineSanitize Silent Valley Mine and verify uranium presence with the spectrometer.
  • Complex / Control CenterConfirm yellowcake authenticity, then interrogate the commander on-site or at Mining Control Center.
  • PortIdentify the container, seize the shipment at Maunga Nui Port, and task the construction-site team to move it to safety.

Equip gas masks before entering Chem-Extraction. Yellowcake is not the main radiological threat at this stage, but inhalation is hazardous.

Recover a shipping manifest or container number through interrogation. If the commander is not at Chem-Extraction, push to Mining Control Center.

Move back to Erewhon, debrief, and clean all gear after handling uranium-linked materials and site dust.

Objective Alpha

Silent Valley Mine

Infiltrate, clear the site, and use the spectrometer to confirm uranium deposits before handing the area to support.

Objective Bravo

Chem-Extraction Complex

Locate the barrels, verify yellowcake authenticity, and secure the production line.

Objective Charlie

Commander Interrogation

Extract the Maunga Nui Port container identifier from the high-ranking commander at the complex or Mining Control Center.

Objective Delta

Maunga Nui Port

Capture the port, intercept the yellowcake container, secure the area, and initiate safe relocation.
