XLink Kai is a program developed by Team XLink allowing for online play of video games with support for LAN multiplayer modes. It enables players on the GameCube, Nintendo Switch, PlayStation 2, PlayStation 3, PlayStation 4, PlayStation Portable, PlayStation Vita / PlayStation TV, Xbox, Xbox 360, and Xbox One to play games across the Internet using a network configuration that simulates a local area network (LAN). It notably also allows original Xbox games to be played online again following the Xbox Live shutdown on 21 April 2010 (similar to that of Save Nintendo Wi-Fi for the Wii) and certain GameSpy titles such as Saints Row 2 to be played online after the GameSpy network shutdown on 31 May 2014.
