First, we will need to grab four Datapoints from around the Base. Here's where you can find each of them:

The first Datapoint we will need is through a vent found in Kotallo's room. Head to the back and find the vent on the left. Climb through the vent, and you will come out into a secret room - the first Datapoint is on the counter in here.

The second Datapoint we need is on the east side of the communal room - the room with the leaf sign above the door. Head in here and find the Datapoint on the shelving.

Head down to the server room, and look to the room on the southwestern side. Head into here, and you can find the Datapoint on a counter at the back of the room.

The last Datapoint we need can be found in Beta's room, which will be unlocked at the end of the story. Head in and pick up the Datapoint next to the hologram of Elisabet, on the right side of the room.

Each of these Datapoints will reference numbers:

With these numbers, we have the code.

Now we have the numbers we need to make up the code, we can head to the locked door.

Inside, you'll find some Datapoints left by those who were originally in this Regional Control Center. Listen to each of them to add them to your Datapoints, and you will have everything from this room.
