About Feature Episodes:
Feature Episodes are grouped into Series and are tied closely together to comprise one story arc. They're available to players of both factions at no extra cost. Each series is comprised of several episodes in a story chain. You must complete the first episode before you can move on to the next. To begin a series, travel to the sector listed in the Contact section of each episode, and you’ll be prompted to talk to the Contact in the lower-right portion of your UI. This Contact will offer you any episodes you are currently eligible to play.
In addition to the standard mission rewards you’ll receive at the end of each episode, there is a special reward available for completing a series during its initial release schedule. For more information about Feature Episodes, please refer to the following helpful links:
