Section 03: R&D Labs

Activate Declassified Mission 11.

Activate the switch at the end of the hall to open the door.

Go inside and immediately take cover (press the cover button to crouch behind walls or objects) (use nearby objects for protection).

In the main area, use the switch near the entry to activate an electricity trap in the small area behind the depression at the far end of the room.

Activate the switch when enemies are in the electricity trap's area to kill them instantly.

Clear the main room of 2-3 Kantuses and 10-12 Drones using the electricity trap and cover.

After the main room is clear, eliminate 2-3 Kantuses, 6-8 Drones, and 1-2 Boomers that emerge from behind the windows on the far right.

Deal with a final wave of 5-6 Drones, one Boomer, and one Kantus emerging from the same windows.

Enter the room on the right side of the main area (where the second and third waves came from).

Go to the back right of the server room and look on the ground to find COG TAG (11/48).

Head to the opposite end of the side-room and go through the automatic door.

Follow the path to the left and hit the switch at the end to open the next door.

Head inside.

On the ground floor, grab any available Frag Grenades, Retro Lancer, Gnasher, or Boomshot.

Hit the green button in the center of the room.

After the cutscene (a non-interactive cinematic the game plays automatically) (non-interactive story sequence), go to the objective marker to continue.
