Campaign play(update) in Empires & Allies

What is the Campaign and how do I play it?
In the world of Empires & Allies, there is more than just you and your friends.  The evil Dark Alliance is always lurking just around the corner looking to bring destruction to your island nation.  The Campaign missions give you the chance to take the fight to the Dark Alliance and ultimately defeat them earning powerful Villain units along the way.
To play the Empires & Allies campaign, click on the strategic map on the main screen.  The map is the globe located in the bottom right corner of the screen.


When you open the strategic map, you will see a number of islands connected by dotted lines. 


The island you are currently on has a large picture of the current boss of the island.


Any island with your flag on it is an island you have liberated from the Dark Alliance. 


To fight on the current island, click the boss picture to bring up the island’s information.  A small screen opens showing the boss, the name of the operation, how many battles have to be fought to win the island, how many of those battles have been completed, what kind and how many units will be fighting in the current battle, and the choices to Fight Now or see further Details. 


When you click on Details a screen like this will open:


You can use this screen to see the details of every mission on the island.  You can enter combat from this screen by clicking on Fight Now!
When the mission opens, you will see the opening screen for combat.  You must choose a certain number of units from your available units, or you can purchase the required units with cash.  In most missions, you must select one or more allies to join you.  These allies can be your neighbors or mercenaries hired for cash. 


When you have selected your units and allies, click Fight to begin.
Some Campaign missions require you to have allies.  Each ally provides one free random Powerup per battle.


To use an Ally’s powerup click on their picture in the lower left corner of the combat screen:


After you use a friend as an Ally in battle, that friend will not be available for combat for another 24 hours.  You can hire a mercenary for cash if you are out of available allies.
In certain Campaign missions, you fight important members of the Dark Alliance.  If you win these battles, you unlock the next leg of the Campaign and gain access to powerful Villain units.  These units are one of a kind and pack an enormous punch compared to the units you can normally build.  When you win these units they are shown in the Reward screen at the end of the battle:
