You can have more than one Base in more than one Warzone using the Multi-Account / Multiple Commanders feature. To create a new Base and still retain your current progress, navigate to the Profile > Settings > Commander menu.
On the Commander page, tap an empty slot to create a new Commander and Base. You'll immediately load into the new game and begin going through the tutorial. Your new Base will automatically appear in the newest open Warzone, allowing you to play alongside new players or friends you've brought to War Paradise without losing your established Base! You can have up to 5 total Bases, including your original.
You can toggle between your Bases any time by returning to the Commander menu and tapping the desired Commander. You will immediately load into the selected Base and be able to continue playing right away.
NOTE: You'll only receive notifications for the account you are currently logged into. Don't forget to log into the account you'd most like to receive notifications for before you go offline, so you don't miss anything important like incoming attacks!
