Following the reveal for how Splatoon 2 will use voice chat, the official Splatoon Twitter account has provided some details on how it and the Switch app will work. Details which were shared in Japanese, but the official tumblr account has provided an English explanation:
“We’ve received a report that Splatoon 2 will be compatible with an upcoming app for smart devices that enhances online play. This app will link with the game and allow you to set a play appointment with your friends and teammates invited through your social media accounts. It also lets you match up with them directly in the game and voice chat with them too.
For example, during a Private Battle, you can voice chat with all of the connected friends when you divide into teams, but once teams are set, voice chat is switched to communication only between teammates in the same team. Also, you cannot communicate with random Inklings you don’t know.”
Splatoon 2 is getting better by the minute!
