A number of the game's achievements reference various popular media:
• The "Rule Ten: Greed is Eternal" achievement is a reference to the Ferengi Rules of Acquisition from the Star Trek series.
• The "No Redshirts Here" achievement, which is earned by making sure no crew members died before reaching Sector 8, is an infamous reference to Star Trek: The Original Series, in which the security officers, who wore red shirts, would often be killed off moments after being introduced.
• The "I don't need no stinkin' upgrades!" achievement is a reference to the popularized-movie version of The Treasure of the Sierra Madre, in which one of the characters makes the statement "Badges? We ain't got no badges. We don't need no badges. I don't have to show you any stinkin' badges!"
• The "Some people just like to watch ships burn" achievement references the Batman film, The Dark Knight, namely Alfred Pennyworth quoting "Some people just want to watch the world burn."
• The "On a Wing and a Prayer" achievement is a reference to the song of the same name, which was popularized during World War II.
• The "Trustworthy Auto-Pilot" achievement icon parodies HAL 9000 from Arthur C. Clarke's science fiction Space Odyssey saga.
