You're an ensign in the Starfleet and you've been assigned to the Enterprise! With Captain Kirk and Mr. Spock, you'll explore amazing new worlds. You might rescue an alien race from a deadly disease, or do battle with a Klingon spy, or time travel to another universe. If you make the right choices, you could be a hero and save the Enterprise. But be careful – or you, Captain Kirk and Mr. Spock could all be in terrible danger! Of course, if you don't like the way your story is going, you can always go back and start a new one!
