We talk a lot about the Super Nintendo ports of Wing Commander here, because they were a major vector for many people to get hooked on the series in the early '90s. Despite that, there were a few major things that generally fly under the radar and haven't been widely seen. One such change is the intro to The Secret Missions. It features an entirely new cutscene talking about the march of the Kilrathi and the development of their new super weapon (which ends up being the graviton weapon employed by the Sivar dreadnought at Goddard). I love the WC1 intro below for its clippy music and downscaled graphics, but you have to check out the second clip with the new Secret Missions vid! You can find more classic game intros at Retro Opening Games. Nintendo World Report TV also recently put out an exhaustive overview of WC on Nintendo platforms, which you can find here!
