The game plays out in two stages. In the first one you get to manage your own army, receive missions from other characters in the game, and scout the enormous world map. Meanwhile, in the second one, you take part in intense turn-based combats with your troops, this is probably the best part of the game.
You will, however, need a Facebook account and a permanent internet connection to play King's Bounty: Legions. Fortunately you can set it up to not publish anything on your wall, making it quite easy to play without 'bothering' all of your contacts with constant messages... as other games which require Facebook do.
The best part of King's Bounty: Legions is the option of challenging your Facebook friends to PvP duels. In these combats you'll have to prove that your tactical skill is superior to your rival's, lest your army be massacred.
King's Bounty: Legions is a very entertaining turn-based strategy game which will prove quite familiar to fans of the franchise. Also, it's not excessively difficult for newcomers thanks to its very complete tutorial in which everything you need to know to defeat your enemies is clearly explained.
