In Wing Commander 1, the Claw Marks (PDF) (the official manual, written in-character) mentions a Terran corvette class called Venture. In the years I've played WC1, I have never encountered one in a single mission and it has thus become a great mystery to me and the people I played it with, whether the Venture actually exists in the game. Was it just a myth? Scrapped before release?
Has anyone seen one and if so, in which mission? I guess the task was to defend it?
Here is a mission tree of WC1 in case you want to refer to a mission specifically.
