The dense nebula of Akhlys Beta.

Akhlys Beta is an isolated area of the Akhlys Arm where the region of space is filled with nebula gases which limits the effects of DRADIS equipment, making it difficult to detect nearby ships and objects and limits visibility.

The single player story mission, Akhlys's Fury: Part 1, takes place in the Akhlys Beta system where each faction must enter into the dense nebula as mining operations are getting ambushed and two mining ships have been lost. It is up to the player to protect the remaining mining ship as they command a patrol squad.
