With Star Trek Online’s fourth anniversary, Perfect World has launched the mid-season update, Season 8.5. From now until February 27, Captains will be able to play a new ‘Featured Episode’ titled “A Step Between Stars,” with Star Trek: Voyager actor Tim Russ reprising his role as Tuvok, now an Admiral.

Star Trek Online is set in the year 2409, thirty years after the events of Star Trek: Nemesis. The peace treaty between the United Federation of Planets and the Klingon Empire, established in Star Trek VI: The Undiscovered Country and strengthened by the Dominion War arc of Star Trek: Deep Space Nine, has collapsed, and both sides are once again at war. The Romulan Star Empire continues to deal with the fallout of the loss of their homeworld twenty-two years earlier (as shown in J. J. Abrams’ Star Trek reboot), while the Dominion was rebuilding its fleet. The Borg Collective has re-emerged as a major threat.

After each playthrough of the event, Captains will be able to choose between one of three pieces of unique ship equipment. They’ll also be rewarded with 400 ‘Qmendations’ on completion of their first playthrough. ‘Qmendations’ are used to unlock one of the newly added Dyson Science Destroyers.
Other events featured in the anniversary festivities include ‘Q’s Party Patrol’ missions in which the player can earn 40 Qmendations each day, along with other cosmetic items.
