Enter The Lock
Land at The Key and meet with Delgado, Mathis Castillo, and the rest of the crew near the landing pad. Head towards the entrance to The Lock. You will be swarmed with Grylloba which will need to be killed to continue. Once it's safe, Delgado will use the keycard he purchased to enter The Lock.

Inside you find The Lock in a bad state of disrepair. Proceed forward and secure the entrance area (Prisoner Transfer) from more Grylloba. Once safe Delgado will tell you and Mathis to head to the control room to try to unlock the doors deeper into the prison. Shortly thereafter, the ceiling will collapse. You and Mathis will be split from the rest of the crew, at which point Mathis will ask you to join him in a mutiny he is planning to do. Regardless of how you respond, you continue deeper into the facility until you find yourself at the control room. Here you lift the security lockdown and discover that Kryx was located in cellblock D. Delgado, still split from you, uses an intercom to ask you to continue on looking for any information about Kryx.

Continue deeper into the facility and restore power to Cellblock D.

Search Cellblock D
Make your way around Cellblock D to the large guard tower on the opposite end of the chasm. Inside, you learn that Kryx was in cell D-03-118 in Section 3. Unlock the cell block(s) and begin searching for Kryx's cell.

Along the way, you can stop by a cell filled with contraband (Cell D-02-105 in Section 2). This cell door is locked but can be unlocked by a lever in the security room above the nearby kitchen.

In Kryx's cell, activate the lamp to discover it has a false base with a note inside. The letter contains information about Kryx's Legacy - a plan regarding a GalBank transport carrying a fortune in credits and his plan for an escape from the Lock. Continue with Mathis to Carter's (a fellow conspirator) locker. Here you find Carter's Gig (Evidence) which contains the code to a supply room where Carter and Kryx dug a tunnel to escape. Follow the tunnel to find yourself in the administration area of the prison.

Escape The Lock
Fight your way through the cafeteria and guards' quarters until you find yourself in the Warden's office. Across the way, in a security room, you can see Delago. Delgado reveals that everyone else has died, and that while he can't open a path for you to join him, he can open the door to the shuttle bay and which contains a shuttle, a way to escape. In this conversation you can tell Delago about Mathis' mutiny, and how helpful you believe that Mathis was. How you respond will affect if Mathis accepted into the Crimson Fleet.

Heading downstairs to the Shuttle Bay, you will need to defeat a Mature Grylloba Queen before the shuttle bay doors open. Once safe, you can use the shuttle to escape The Lock and return to The Key.

Talk to Delgado onboard The Key, who will welcome you into the crimson fleet and reveal their next heist, much to Naeva's annoyance. Speak to Mathis, who either thanks you or threatens you based on what you tell Delgado, and then discuss the situation with Naeva.

Finally, if you are still in good graces with SysDef, return to the UC Vigilance to update them on Delgado's plans. They decide to let the next heist play out instead of trying to stop it.
