The Star Trek Online site has been updated with the news that current and lapsed subscribers will be able to take advantage of the new F2P iteration beginning Thursday, January 5th. They will have access to the Silver level of the game for one month.
Starting tomorrow (Thursday, January 5th), anyone with a lapsed subscription to Star Trek Online will be able to log into the game and play as a Silver member. This means that any account that has in the past subscribed to the game, even if only for the initial month, can come back and play for free!
