About Street Fighter II

The player fights opponents in one-on one combat in a string of best two-out-of-three matches. The goal of each round is to diminish the energy level of your opponent before the timer runs out.  If both fighters have equal vitality left, it will lead to a ''draw game' or a 'double KO'.  A that point, the fight will continue for additional rounds until sudden death.
