Side Missions

Beyond the main campaign, the Oldest House is rife with secrets and anomalies that demand the Director's attention. Side Missions in Control offer valuable rewards, expand the lore, and often unlock new abilities or powerful modifications. This section provides detailed walkthroughs for each side mission, ensuring you don't miss a single hidden gem.

A Matter of Time

Location: Maintenance Sector, Janitor's Office

Trigger: Speak with Ahti after completing the main mission "Directorial Override."

This mission involves helping Ahti with his plumbing issues, which are, as expected, far from ordinary.

  • Step 1: Locate the Clogged Pipes. Head to the Maintenance Sector. Ahti will mark three locations on your map: the Water Treatment Plant, the Pump Station, and the Coolant Pumps.
  • Step 2: Clear the Water Treatment Plant.
    • Navigate to the Water Treatment Plant. You'll encounter Hiss forces guarding the area. Clear them out.
    • Look for a large, glowing red pipe. Use your Launch ability to pull the debris blocking it.
    • Be prepared for a surge of Hiss after clearing the pipe.
  • Step 3: Unblock the Pump Station.
    • Proceed to the Pump Station. More Hiss will be present.
    • Locate the two smaller, red-glowing pipes on opposite sides of the room. Use Launch to clear both.
    • A shielded Hiss Elevated will likely appear here; prioritize taking down its shield with Launch or Pierce.
  • Step 4: Fix the Coolant Pumps.
    • Travel to the Coolant Pumps area. This section is often heavily infested.
    • There are three pipes to clear here, one on the upper level and two on the lower level.
    • The upper pipe is accessible via a platform. The lower pipes are near the main coolant machinery.
    • After clearing all three, a Hiss Cluster will spawn. Focus fire on it to prevent reinforcements.
  • Step 5: Report Back to Ahti. Return to Ahti in the Janitor's Office. He will reward you with Source Energy and a Mod.

Old Growth

Location: Research Sector, Central Research

Trigger: Interact with the research notes in the Central Research area after completing "My Brother's Keeper."

This mission delves into the strange plant life that has begun to infest parts of the Oldest House.

  • Step 1: Investigate the Growth. Follow the mission marker to the Botanical Lab within the Research Sector.
  • Step 2: Contain the Spores.
    • Inside the Botanical Lab, you'll find several large, pulsating spore sacs.
    • You need to destroy these sacs before they release more Hiss. Use your Service Weapon or Launch.
    • Be wary of the Hiss Charged that will emerge from the sacs as you destroy them.
  • Step 3: Activate the Purifiers.
    • After clearing the spores, locate the three Purifier Control Panels in the lab.
    • Each panel requires you to solve a simple environmental puzzle, usually involving moving a power core with Launch to its receptacle.
    • Once all three are active, the air will clear, and the mission will update.
  • Step 4: Collect the Research Data. Find the Research Data Drive on a desk near the main console in the Botanical Lab.
  • Step 5: Deliver to Dr. Darling's Office. Take the data to Dr. Darling's Office in the Executive Sector. Place it on the designated terminal. You will receive Ability Points and Crafting Materials.

Fridge Duty

Location: Panopticon, Cell 717

Trigger: Speak with the distraught scientist, Langston, in the Panopticon after completing "Threshold."

Langston needs help with a particularly troublesome Object of Power: a refrigerator with a dark secret.

  • Step 1: Reach Cell 717. Navigate to the Panopticon's Cell 717. Be prepared for a challenging encounter.
  • Step 2: Confront the Fridge.
    • Upon entering Cell 717, you'll find the Refrigerator Object of Power.
    • The fridge will manifest as a powerful Hiss entity, often a Hiss Distorted or Hiss Warped.
    • Utilize your Shield ability and powerful weapon forms like Spin or Pierce to deal with it effectively. Keep your distance and use Launch for heavy damage.
  • Step 3: Contain the Object. After defeating the Hiss manifestation, approach the refrigerator and use your Interact ability to contain it.
  • Step 4: Report to Langston. Return to Langston in the Panopticon to receive your reward: a unique Weapon Mod and Source Energy.

What a Mess: Clear the Mold

Location: Maintenance Sector, Janitor's Office

Trigger: Speak with Ahti after completing "A Matter of Time." This is the first in a series of "What a Mess" missions.

Ahti needs you to clean up various manifestations of Mold throughout the Oldest House.

  • Step 1: Head to the NSC Power Plant. Ahti will direct you to the NSC Power Plant in the Maintenance Sector.
  • Step 2: Destroy the Mold Hosts.
    • Enter the Power Plant and locate the areas infested with glowing orange Mold.
    • You'll need to destroy several Mold Hosts – large, bulbous growths that spawn Mold enemies.
    • These areas are often heavily defended by Mold-corrupted Hiss, including Mold Hosts and Mold-1 (a unique, powerful Mold enemy).
    • Focus on destroying the Mold Hosts first to stop the enemy spawns. Use explosives or powerful Launch attacks.
  • Step 3: Cleanse the Area. After all Mold Hosts are destroyed and the area is clear of enemies, the mission will update.
  • Step 4: Return to Ahti. Speak with Ahti for your reward: Source Energy and Crafting Materials.

Note: There are several "What a Mess" missions. Ahti will provide new objectives as you complete previous ones and progress through the main story. Each typically involves clearing a specific area of Mold or Hiss and rewards you with valuable resources.
