Prior to Splatoon 2’s official reveal, clips of the game were featured in the announcement trailer for the Nintendo Switch, the game’s native console. Its unanticipated appearance led to speculation by the media and public over whether or not the footage shown was that from a port of Splatoon or a sequel. It was also presented in the trailer in a way that promoted the game as an eSport, following investments by Nintendo in Splatoon eSport tournaments in late 2016.
A limited-time global multiplayer demo for the game, known as the “Splatoon 2 Global Testfire”, was made available to play in March 2017. Similarly to the demo of the original game, it was only available to play for a specific time period: six one-hour play sessions across one weekend. Only two maps and four weapon sets were available to use. These play sessions were shared worldwide, allowing for testing of the global servers. The game is set for release worldwide on July 21, 2017.
