Yeah, I wonder, too. The rail system led into the tunnel that headed west toward the base of the terraforming installation. I sent ScoutDrone1 down it to verify and kept ScoutDrone2 hovering over my head to watch my back. The other tunnel went off toward the northeast at an angle that was odd, considering the orientation of the rest of the space. I couldn’t see into it from here so I started across the floor, my boots losing traction in the soft dirt we’d just let in.
