When you start, quickly spin around and you’ll find a Data Pad behind where you first came in. After you grab it, make your way forward, but look to a pillar on the left for yet another Data Pad. It’ll have a ring shape at the top, so it’ll be easy to spot.
From there, scan the area with your D-pad and you’ll locate a few other collectible items in the area. Once you’re done, track down Dr. Halsey, who will lead you to another cut scene. This concludes the mission.
