To acquire the Joint Projects Director Keycard in Call of Duty: Black Ops 6’s Emergence mission, follow these detailed steps:

### Step-by-Step Guide

1. **Enter the West Wing First**
– Start by entering the West Wing of the facility. This will give you access to the necessary areas and tools needed to progress.

2. **Use the Computer and Enter ‘Access’ and ‘Lift’**
– Use the computer in the West Wing to access the lift. This will help you navigate to the East Wing where the Joint Projects Director Keycard is located.

3. **Acquire the Grappling Hook**
– Once you have access to the lift, go up to the area where you can acquire a Grappling Hook. This tool is crucial for reaching high platforms and navigating through the facility.

4. **Defeat the Abomination Mini-Boss**
– After acquiring the Grappling Hook, proceed to defeat the Abomination mini-boss. This will unlock further areas in the East Wing.

5. **Place the Advanced Combat Research Card**
– Place the Advanced Combat Research card in the central hub of the East Wing. This step is necessary to unlock additional areas.

6. **Enter the East Wing and Approach the Joint Projects Entrance**
– Enter the East Wing and approach the Joint Projects entrance. You will see a locked door with a camera above it.

7. **Use Your Grappling Hook Above the Entrance**
– Look up and use your Grappling Hook above the entrance to reach a higher platform. This will allow you to access the room ahead.

8. **Enter the Room Ahead and Face Off Against the Mimic Mini-Boss**
– Continue straight forward and enter the room ahead. Be prepared for an enemy jumpscare and face off against the Mimic mini-boss to get the Joint Projects Director Keycard.

### Additional Tips

– **Handling the Mimic Bug**: If the Mimic does not spawn, you can try loading up your last checkpoint to refresh the mission. This may help resolve any potential bugs.
– **Navigating Dark Areas**: The room where you find the Mimic can be dark and filled with many objects, making it easy to miss the Mimic’s location. Keep a sharp eye on shaking objects or reload the checkpoint to get a refresher.
– **Completing Other Director Keycards**: To complete the Emergence mission, you need to locate all four Director Keycards. The Cognitive Research Director Keycard can be found by draining the Cognitive Research Pool and using your Grappling Hook to reach the Drainage area. The Administration Director Keycard can be found by collecting four reports for the Director in the Administration building.

By following these steps, you should be able to acquire the Joint Projects Director Keycard in Call of Duty: Black Ops 6’s Emergence mission.
