- Nintendo Switch Online app will offer a “SplatNet 2” service within the overall app, which will provide private lobbies, voice chat, stat tracking, and more for the upcoming squid / kid team shooter.
- Once the full online service rolls out next year, players will have to pay $19.99 per year to access online multiplayer and use the Nintendo Switch Online app. That fee also includes access to a library of classic Nintendo games on the Switch.
- And yes, it’s still ridiculous that you’ll need to use a standalone smartphone app for voice chat instead of it simply being built into the Switch itself, but that’s Nintendo for you.
