Energy Cells are used by the Federation as portable power sources, capable of delivering enough juice to nearby equipment to run for some time. Upon arriving at the GFS Valhalla, you'll discover a number of damaged systems in need of an Energy Cell to restore power and proper function. You'll need to locate all nine Energy Cells throughout the game to fully access every corner of the Valhalla and retrieve the vital data needed for the success of your final mission. Keep an eye out for small hovering data stations throughout the Valhalla; each one provides clues on where to find the corresponding Energy Cell hidden out in the wild.
