It was announced earlier that Splatoon 2 will let up to 8 users connect through local wireless and enjoy playing together. Now it’s been revealed Splatoon 2 will also allow 8 players get together using LAN Play for those looking to set up a Private Battle without needing a wireless connection. This will make it easier for players to put together their own tournaments any time they want as long as they’re willing to set up LAN Play. Additionally, players will be able to use spectator mode during LAN Play, as long as they have one or two addition Switch systems available.
