If one player decides to fight in real-time instead of auto-resolving a battle, the other player joins the fight on their team. The owner of the army can then delegate control of some of their units to their teammate. This system brings a lot of fun and strategy into the game.
The decisions in the game sometimes have little context even though they may result in large consequences, which makes the decisions difficult as there is no way to know the reason to make them or how they will end up.
Each mission in the campaign plays out slowly and requires careful planning, slight mistakes and the game is not that forgiving. this means the player must give full attention to the game and its enthralling story as it unfolds.
