ZeRO app for Android

Your in-game friends and whispers on your phone: see who is online, chat, and get notifications even when the app is closed.

What it does
  • Who is onlineHow many players are in the game and in the app, the online list; friends — in the game, on the phone or offline.
  • WhispersChat with players just like in the game. Players who are offline get your message when they log in (up to 7 days).
  • NotificationsA whisper, a friend logging in, a friend request — even when the app is closed. Game sounds, vibration, quiet hours.
  • Same accountLog in with your login and password or with Google — the same account as in the game. The login is remembered for 30 days.
