Fighting games have evolved in increments over the years, and while each instalment has brought minor improvements on the competition and its predecessors, the mechanics and gameplay have always been more or less the same. Tekken has always opted for a slightly different approach to its control system. Where games such as the Street Fighter and Mortal Kombat series gave the options of strong, medium and hard punches and kicks, Tekken has always assigned a button to each limb, and this allows players to create a flow of natural body movement in a way that no other game has ever managed.
