With the addition of online multiplayer, our plan for offline mode is to create a truly offline mode. This means that until you click the “Play Online” button, no data is sent across the internet. No account login, no account check, nothing. Fully offline. This means offline (which will become fully offline) cannot support connective features such as chat, leaderboards, or the cosmetic shop.
