Arc Games offers an official launch trailer for the upcoming Agents of Yesterday expansion for Star Trek Online, the Trekkie MMORPG (thanks Perrin42). This will bring Chekov and Scotty into the game along with the original USS Enterprise, who will play into the time travel themes the add-on will introduce, and the description tells us this will launch on July 6th. Word is: "Travel through both space and time as you fight for our very existence. The Temporal War rages with Krenim and Na'kuhl forces working to undo the very fabric of time and us with it. Join the Temporal Defense to aid in the protection of our worlds on all fronts, before we are wiped from history itself."
