Street Fighter IV/Walkthrough

The game takes place after the Street Fighter II tournament, but before Street Fighter III.

The arcade version of Street Fighter IV features all twelve World Warriors from the original Street Fighter II as part of the regular roster, along with four new characters (C. Viper, Rufus, Abel and El Fuerte). The game also introduces a new boss character named Seth. Seth becomes selectable after completing the arcade mode with all of the selectable characters, including Akuma and Gouken.

Two hidden characters are featured in the game. One of them is Akuma, who is both, a hidden challenger, as well as secret selectable character. The other is Gouken, Ryu and Ken's sensei, making his official debut in a fighting game. Gouken appears as a secret challenger, if you are able to defeat him he becomes selectable.

The home versions will feature all the characters from the arcade, as well Fei-Long, Dan, Sakura, Rose, Cammy and Gen. Seth can be unlocked as a playable character in the home version of the game, too.

Returning cast

 * M. Bison: Seeing himself as the rightful dictator of the world, M. Bison appreciates the power of the human fighting spirit, and technology's ability to enhance it, over firearms and weapons of mass destruction. After his body was destroyed in the second Street Fighter tournament, M. Bison returns with a new body in an effort to co-opt the tournament to further his own diabolical plans.
 * Ryu: Unable to turn down any opportunity for a good fight, Ryu eagerly enters the next Street Fighter tournament for a chance to train harder and expand his fighting abilities beyond all limits. But could this tournament be an elaborate trap to capture this fabled fighter?
 * Sagat: It's been many years since Sagat's defeat at the hands of Ryu. Sagat realizes that there is more to fighting than just winning, but he is still striving to figure out what that is.  Perhaps he will find the answer in the next tournament.
 * Vega: Never quite content with the boring aristocratic life he returned to after the fall of Shadaloo, Vega sees the creation of a new tournament as a chance to immortalize not only the original organization, but his youth and good looks as well.
 * Zangief: Having already proven his greatness to his home country once before, Zangief is prepared to repeat the feat in the latest tournament. And this time, he's not just doing it for home and country, he's doing it for a new young friend as well.

New characters

 * El Fuerte: El Fuerte is a Mexican fighter with two passions: traditional Mexican wrestling and cooking. He seeks the exhilarating thrill of giving everything he has and improving his talents at both.
 * Rufus: Reviled by the fact that Ken Masters is considered the greatest fighter in America, portly Rufus enters the tournament determined to prove once and for all that it is really he who is best. And if he gets a chance to kick Ken's butt on national TV, so much the better.

Hidden characters

 * Gouken: Thought to have been long dead, the master of Ryu and Ken, and the brother of Akuma, mysteriously reappears and shows up at the latest tournament with an unspoken goal: to seal one's awakening chi with the Power of Nothingness before it is too late.

Boss

 * Seth: A creation of the S.I.N. organization, a synthetic being, Seth was originally known as Number 15 until he gained greater self-awareness and overthrew his creators. Continuing on with their plan, he intends to succeed where M. Bison has failed.
