The expansion serves to bring fans of Star Trek and Star Trek Online closer to Star Trek: The Original Series, which starred William Shatner as James T. Kirk and Leonard Nimoy as Spock.

Steve Ricossa, executive producer of the game, stated in the press release:

Players will be able to take control of a Captain from the original series and visit locations taken directly from the show, such as Taurus VII and the Gorn Rock Planet Edren.

New playable starships taken from the TOS era, like the Daedalus class Science Vessel, will also be implemented.

Immersing players all the more into the expansion, Chris Doohan will be voicing Scotty – following in his father James Doohan’s footsteps, and Walter Koenig will be voicing Chekov.

The expansion will be launching this summer.
