We decided to put YOU into the game as a General, personally commanding your armies. After a few upgrades (first starting with just 50 SP), General will provide bonus stats to all/certain units in his stack.
You can personalize your General by uploading a custom icon. Go to the Edit profile
page, it's right next to the avatar upload.
There are also several rare commanders (similarly giving boost to their stack units), as well as special rare units specializing in assassinating commanders.
Generals are only available to Premium members
