Fullmetal Alchemist: Dual Sympathy integrates an innovative twist via the use of alchemy - which is the ability to transform objects from one form into another - and its strategic impact on the game. Whether repelling defenders, removing obstacles or engaged in battle, all six characters have unique and devastating alchemy attacks, which range in scope from bolts of fire and stone spikes, to monstrous cannons and gigantic fists. By holding down the alchemy button on the Nintendo DS touch screen, players can transform their initial alchemy creation into a mega-weapon of tremendous proportions and impact.
