The fourth episode of The Expanse: A Telltale Series is quite short and has far fewer collectibles than the previous chapters. While you don't have to search for items, there are still four scans you can make if you want to see everything there is to discover aboard the Cassiopeia Station.
Drummer has limited mobility in this chapter, so searching every corner can take additional time. We recommend traveling in zero gravity whenever possible, as Drummer loses the ability to run after entering the mines.
Transmission Log
In the Cassiopeia Cathedral (the room where you start), go to the back left of the room. There are some computer benches along the wall; the one on the far left contains daily broadcast logs for the collectives.
Equipment Registry
In the mine shafts, take the side tunnel shortly after you enter. It is located on the right side if you remain upside down in zero gravity or on the left side if you turn around and move along the floor. You will come to a dead end with a cart that you can scan.
Mineral Yield
At the first lever that opens a door, look behind you and to the left. There will be a panel that you can scan. It might be obscured by a floating container, so carefully check the wall.
Tunnel Analysis
In the room with the surveillance drones, go to the corner to the right of the exit door. There, you will see a floating platform near the bottom of the chamber that you can scan. Make sure to collect it before landing; otherwise, a cutscene will be triggered, and the door will close behind you. If this happens, you will have to restart the chapter if you want to find the tunnel analysis or other logs you may have missed.
"If you manage to traverse the room without being detected by the drones, you will receive the "Drone Dodger" achievement/trophy."
