If you ever owned an Xbox back in the early days, you'll know exactly what System Link is, and as demonstrated in the video above, it still works for multiplayer games across all four generations of Xbox consoles in 2020.
The feature allows multiple consoles to connect together for offline multiplayer games via a Local Area Network connection, which was supported by a large array of titles on the original Xbox and Xbox 360.
Modern Vintage Gamer shows System Link working with the backwards compatible title Crimson Skies on an original Xbox, Xbox 360, Xbox One and Xbox Series S, allowing you to play four-player multiplayer with no fuss.
We can't imagine too many people will get much use out of this feature these days, but it's a very cool option to have, especially if you've got a few Xbox consoles sitting around the house gathering dust.
