Mastering the Black Ops 6 Emergence Mission: A Comprehensive Guide
The Emergence mission in Call of Duty: Black Ops 6 marks the campaign's halfway point and represents a significant departure from traditional gameplay. This guide provides a complete walkthrough.
Navigating the Kentucky BioTech Facility
The mission begins with Case and Marshall entering a Kentucky BioTech facility filled with toxic gas, necessitating gas masks. An elevator malfunction leads to a fall, gas mask breakage, and subsequent hallucinations. The player regains control after a cutscene.

Locate a locked red-lit door. Use a hatchet found on a mannequin to break it open. Proceed through the hallway, up the stairs, and to a central elevator.

Activating the elevator triggers a zombie encounter (hallucination). Defeat them with the hatchet. A phone call directs you to the biotechnology room, requiring four director's cards (Red, Green, Blue, Yellow). A map indicates the Yellow card's location.
Acquiring the Yellow Card and Grappling Hook
From the security console, follow the map to a yellow staircase. Solve the computer puzzle in the Director's office (answers: "Access" and "Lift"). More zombies appear in the A.C.R. room.

A mannequin holding the Yellow card transforms into an abomination. Before engaging, collect armor, weapons, and the crucial grappling hook. Use explosives (C4 or grenades) to eliminate the abomination and its zombie horde. Retrieve the Yellow card.
Securing the Green Card
Use the grappling hook to ascend to the main facility. Locate the Administration Facility (grapple up from the security desk). Answer the phone; you need to find four documents and place them in the file display area.

Mannequins will pursue; sprinting and turning keeps them at bay. Document locations: a desk in the corner, near a round table, on a small center table, and in the cafe near a sink. After placing the documents, grapple the red mannequin repeatedly until it transforms into a Mangler Zombie. Defeat it to obtain the Green card.
Obtaining the Blue Card
Grapple across to the Joint Projects Facility. Answer the phone. Locate the glass chamber and the Blue card. A mimic will spawn; shoot moving objects to reveal and eliminate it. Retrieve the Blue card.
Retrieving the Red Card
Head to the East Wing (marked on the map), following the red carpets to stairs and a room with water, a console, and a Mangler. Interact with the console to reveal the Red card.

Use the grappling hook to reach the upper area, jump into the pool, and swim through the red tunnel. Climb the ladders, eliminate zombies, and unlock the door using the blacklight code. Activate the timer and turn all drain switches within 25 seconds. Defeat the Mangler and its horde to get the Red card.
Confronting the Disciple
Return to the security desk, insert all four cards, and take the elevator. Fight off zombies. Answer the phone in the BioTech room, engage the horde and the Disciple. The final cinematic reveals the events were a hallucination.
