The attackers will begin the combat on the left side of the screen, with a field seperating them from the defenders on the right side. In Heroes III, creature banks are an exception, as the attackers begin in the center of the field, with the defenders around them. The combat phase is turn-based, with every creature performing one action per turn, and the creatures with the highest initiative or speed acting first. In Heroes V, this has been replaced by a ATB (Active Time Bar) that reveals which creatures will act next, and allows fast creatures to perform more actions than slow ones.
