What is more - players that participate in the Open Beta testing phase of Knights of the Sky will receive a special in-game bonus! This bonus will consist of extra items when the game is officially launched.
Knights of the Sky features two different factions from which the players will have to choose. Once decided, you will be challenged to fight for faction by conquering territories and capturing locations. You can do this by recruiting troops, utilizing powerful heroes and upgrading you sky castle.
Of course, like other games in the genre, you will also have to collect resources and research new technologies in Knights of the Sky. If you fail to do so, you could find yourself quickly losing ground in the fight for your nation and ultimately, the war.
