Some more on Salmon Run. Online play is event-based and can be enjoyed during times when Grizzco Industries is open for business.
In Splatoon 2, there are two ways to play Salmon Run: local multiplayer and online.
Local multiplayer lets you play anytime, anywhere. When you don’t have enough players gathered locally to start a full 4v4 Turf War, Salmon Run is great option.
Online play, on the other hand, is event-based and can be enjoyed during times when Grizzco Industries is open for business.
