We are approachig the big cross platform update. This changes the battle system, replacing single units with crews that are shown as cards.
The crew cards are used to spawn your offensive units and power-up into the fights. This makes spawning faster and more effective.
The latest update is taking us towards the changes, meaning that Android players no longer have single units.
I'm an Android player! How can I fight!
You should see a chest which contains your crews that will replace and compensate your single units. This chest can be found in the right corner of your stronghold's HUD, under the special offer chest, above the attack icon.
If you can't see the chest, closing and restarting the game should help and the chest should become visible.
However, if you still can't see the crew chest, contact firstname.lastname@example.org
I'm an iOS player! I can't see any of this!
That's correct. The latest update was for Google Play, and we release the changes globally and in iOS when we have made sure that everything works. This prevents any larger frustration in players if there would be something that needs to be tweaked. But worry not! It's not gonna be long anymore before the changes are available for everyone.
