It is stardate 3744 and the Federation is being attacked by Klingon invasion force. As captian of the Federations Starship Enterprise, it is your mission to find and destroy the enemy forces before time runs out.
Harken back to the early days of computers, when computer games were text based, and the StarTrek television show was still new. If you are over a certain age (that wont be mentioned), then you probably played this game on a Green Screen terminal, or a clattering teletype machine. And if you are younger than that "age", then StarTrekDS will give you a retrospective view of how things began.
So board the USS Enterprise® and take command, defend the galaxy from the merciless invaders.
