Star Trek Online is going to be in reruns on May 16th, and unlike television shows, this is a good thing. The featured episode reruns allow players to pick up special items that aren't obtainable in the game through any other means, including Breen and Reman bridge officers for Federation and Klingon captains and Lobi crystals for everyone.
The event runs from May 16th until May 27th, with each featured episode series (Spectres, Cloaked Intentions, The 2800, and Cold Call) providing a special reward for characters that complete them. Players can also earn 15 Lobi crystals for completing at least one episode per day, making for a total of 180 available for free during the event. So if you haven't gotten the special rewards on a character, you want some crystals, or you just feel like going through some classic Star Trek Online missions, you'll want to jump in on the reruns.
