Star Trek Online is pretty happy with how this past summer went. Sure, seasons are kind of a meaningless concept when you're talking about a setting that spans multiple planets with their own annual cycles, but the players are still here on Earth, and they can celebrate the end of the season with free stuff.
An as-of-yet undisclosed ship will be going live in the game's cash shop tomorrow, but that's not the really free part. From August 29th to September 1st, around 1:00 p.m. EDT, a new promotional item will be flagged in the store as free. These items are all account-wide unlocks so long as an eligible character is available to claim the item. Who wouldn't like some free stuff for the end of summer?
[Update: The team has also today released more information about upgrading tier 5 ships.]
