Step-by-Step Walkthrough for All 4 Stages

To successfully finish the active matter optics in the dark investigation, you must navigate four distinct objectives located within the Shegolskoe map. Each stage uncovers more about the fate of courier Viktor Arsentyev and the terrifying biological anomalies lurking in the shadows.

Stage 1: Recovering the Courier's Bag

Your first major objective requires you to locate and extract the courier's bag from Viktor's apartment in Shegolskoe. Because extraction shooters reward map knowledge and noise discipline, make sure you clear adjacent rooms before interacting with containers.

  • Objective: Find and extract Courier's bag from the apartment.
  • Requirement: 10 Monolith Token bypass.
  • Reward: 800 Credits.

Stage 2: Gathering Symbiotic Samples

Once you secure the bag, the Agency requires biological samples that display unique signatures uncharacteristic of standard Dalniy active matter. Analysis reveals that these samples formed in close symbiosis with a living organism, carrying altered DNA traces from Arsentyev.

  • Objective: Collect and extract 50 Active Matter units.
  • Requirement: 10 Monolith Token bypass.
  • Reward: Refiner fuse recipe for the PK-AV Collimator.
Stage Number Task Description Reward Output
Stage 1 Extract Courier's bag from apartment 800x Credits
Stage 2 Collect & extract 50 Active Matter PK-AV Collimator Refiner Recipe
Stage 3 Photograph 2nd-floor stairwell anomaly 1x First aid kit, 10x Healing ampule
Stage 4 Eliminate 2 Invisibles in Shegolskoe 1x Steel armor plate (S)

Stage 3: Documenting the Stairwell Anomaly

The anomaly causing the strange light distortions needs visual confirmation. You must return to the second-floor stairwell in the Shegolskoe apartment building to capture photographic evidence of light scattering in the yellow-to-blue spectrum.

Watch Your Angles Taking photographs leaves you stationary and vulnerable. Clear the stairwell completely of AI threats before pulling out your camera tool.

Stage 4: Eliminating the Threat

The final combat hurdle of the active matter optics in the dark investigation requires you to hunt down and eliminate two Invisibles hiding inside the three-story apartment building. These entities utilize the environment's spatial distortions, making quick target acquisition difficult.

Rewards and Crafting Unlocks Breakdown

Successfully completing the active matter optics in the dark investigation yields some of the most beneficial early-game crafting unlocks available in the franchise multiverse. Instead of wandering aimlessly through high-risk raids, completing this Kestrel Modular Works questline guarantees tangible upgrades for your base of operations.

Upon turning in the final quest steps, players receive a substantial bundle of resources that directly feed into the game's refining and crafting economy:

  • 20x Crystallized Active Matter
  • 1x PK-AV Collimator (Pre-built experimental sight)
  • PK-AV Collimator Replicator Blueprint

According to community testing shared across extraction shooter forums, utilizing the PK-AV Collimator significantly improves target acquisition in low-light environments, giving operators a distinct tactical advantage during night raids or unstable weather conditions.

Common Mistakes and How to Avoid Them

Even seasoned extraction shooter veterans can fall victim to avoidable errors during this questline. Review these common pitfalls to ensure you extract with your loot intact:

  1. Rushing the Stairwell Photo: Players often attempt to snap the Stage 3 photo while enemies are still patrolling the hallway. Always clear the floor first.
  2. Ignoring Backpack Greed: Trying to haul too much extraneous loot while carrying the courier's bag slows down your movement speed, making you an easy target for hostile environmental anomalies or other players.
  3. Forgetting Bypass Tokens: Ensure you have enough Monolith Tokens for the stage requirements before deploying into Shegolskoe.
Common Mistake Consequence Prevention Tip
Rushing Room Entries Ambushed by Invisibles Pie every doorway and listen for audio cues
Over-encumbrance Slow movement during extraction Prioritize quest items over standard scrap
Ignoring Healing Items Quick death from anomaly ticks Always stock up on healing ampules before raid start
