When adventurers go into an adventure, they're usually fairly certain they're going to win. At least, I don't think too many groups head into one going, "Woo! Come on, TPK!! Woo!" However, that might be the case with this one. The classic, unwinnable simulation, the Kobayashi Maru is now available as a free adventure download for Star Trek Adventures from the Modiphius website.
From the website:
