Ancient Warfare engine provides a hex based, tactical, plot, simultaneous resolution execution. A game turn is composed of three phases: (1) The player assigns commands to his units (movement, changing formation etc). (2) The program then determines the net effect of these orders as the move is played out. (3) Finally, units move, fire at each other, and engage in melee combat. The players watch the outcome of their decisions as a turn of action unfolds. The game then moves on to the next turn.
