There are 3 types of Chats in the game.
Global Chat includes players from all over the world. You can use the Global Chat to ask questions about the game, or to find new Alliances to join. Occasionally, updates relating to Resource Caches, Black Sites, and Alliance HQs will be posted in the chat as well.
Regional Chat allows you to chat with players who speak the same language as you. You can select the language of your choice by tapping the flag icon in the top right corner of the screen.
Alliance Chat is intended for all Alliance members to converse together. However, Alliance Members with Chat admin rights can create new Chats where only members of a certain Alliance Role may participate.
Please note that you must be respectful and courteous to other players at all times in the Chat. Disrespectful and uncourteous behaviour includes spamming, using foul or abusive language, and insulting other players.
Should you fail to conduct yourself in an appropriate manner, you will be banned from the Chat.
