UNC: Depot Sigma-23 Walkthrough

After learning about the Rachni outbreak after an automated supply delivery, travel to the Gorgon system in the Argos Rho cluster. Board the Unidentified Space Facility. There are no Enemies at the entryway, so head to the main hold of the ship.

You will find a single Rachni Soldier, located on your left once you enter the room, and 7 Rachni Workers. Clear the Rachni Soldier first as it is the greatest threat and then focus on the Workers. Once the hostiles are down, turn around to hack the two Weapons lockers.  After that, keep moving forward.

On your way, you will find more containers. First a secure crate that requires Average Decryption, a wetware kit hidden in an alcove, a technician kit, before the door to the forward section there is another locked crate that requires easy Decryption and around the corner, you will pick up an upgrade kit. Head through the door.

Head to your right to obtain a medical station that requires easy Decryption, a crate, 2 storage lockers and an upgrade kit. You won't find anything at the cockpit.  Now head to the left module. There you will find a terminal with data logs by Major Elena Flores. Listen to the logs to learn about what happened here.

  • The first log describes the station as an operational one, stating that they will be adding barracks and stocking munitions. 
  • The second entry describes the arrival of the package and how different these are supposed to be. Flores documents a plan to test the Rachni on some local Pirates.
  • The third and final entry, describes that the Rachni have escaped. They accessed freighters going to random destinations. Flores tells someone referred to as General,  to "Screw the Rachni" and destroy the station.

Next to the terminal you will find some demo charges, ONCE you access the terminal, you will have 70 SECONDS to get back to the Normandy in one piece. Before preparing to set the charges, make sure you are not leaving anything behind. Once you do, set the charges and run!

At the moment you arm the charges, more Rachni will spawn to block your access back to the Normandy. Five Rachni Workers and a Rachni Soldier will be waiting outside the door. Send in your squadmates first, and then follow them. Take the Rachni as fast as you can, and head to the Normandy. Once you reach the Normandy, keep going until you leave  the planet because the clock doesn't stop, and only once you do, the Assignment will be labeled as completed.
