Bio-Acoustic Key: Containment Block access and sound-based doors

Category: Exploration

Field Complaint

I cannot get into the Containment Block. There is some weird sound-based lock that I do not understand.

Validated Response

The Bio-Acoustic Key is your ticket into the Containment Block and other sound-based security doors — it is tied to Main Objective 17, 'Access the Containment Block.' Take the main elevator to Level 2 in Cascade Labs, then head to Containment Block DIRAC. Take the first door on the right and look for the whiteboard outside Containment — it outlines where you need to go. Some areas inside require a Level 3 security lock, so have your Keypad Hacker ready. There are preset retreat triggers in certain areas, meaning enemies will chase you out if you linger too long in the wrong spot, so keep moving and do not treat Containment like a casual looting stroll. Reserve inventory space for the key before you go — nothing worse than getting there and realizing you cannot pick it up because you stuffed your pockets with junk. After you reset the security system, you can open the containment cells, which contain useful items like the Shotgun Chair and Lettuce. If you get caught out of cover, use your shield and reposition — standing still in Containment is how you die. Plan your route using the whiteboard, move with purpose, and get out before the respawn timers catch you.

Summary

The Bio-Acoustic Key unlocks Containment Block DIRAC. Follow the whiteboard instructions outside the entrance.
