Short answers, pulled from the story.
The parry system in Street Fighter III is a high-stakes defensive mechanic that allows players to deflect any incoming attack without taking damage if timed perfectly. This system requires the player to move the controller toward or down at the exact moment an opponent's attack is about to connect. Success leaves the opponent vulnerable for a counterattack, while failure results in taking full damage.
The development team for Street Fighter III was led by producer Noritaka Funamizu and character designer Akira Yasuda. The new roster included characters such as Alex, Dudley, Elena, Ibuki, Oro, Yun, and Yang. Akira Yasuda later expressed regret about working on the game, stating that if he could change the past, he would rather not have worked on it at all.
Each character in Street Fighter III is made up of approximately 700 to 1,200 individually drawn frames of animation. These frames run at 60 frames per second to create elaborate 2D sprites using the CP System III hardware. This level of detail was unprecedented for the time and included multiple hit stun sprites.
Gill is the leader of the secret organization Shadowlaw and serves as the main antagonist in Street Fighter III. He is the final opponent for all characters in New Generation and 3rd Strike, and for most of the characters in 2nd Impact. Gill manipulates fire and ice to devastating effect and seeks to turn the Earth into a utopia.
Street Fighter III: 3rd Strike was released in 1999 as the final installment of the trilogy. It followed Street Fighter III: New Generation and Street Fighter III: 2nd Impact, which both launched in 1997. The 3rd Strike iteration refined the mechanics and added new Super Arts to the game.
The music for Street Fighter III was composed by Yuki Iwai for New Generation and 2nd Impact, and Hideki Okugawa for all three games. Canadian rapper Infinite contributed three songs and announcer tracks for 3rd Strike. The soundtrack was released on CD by First Smile Entertainment in 1997 for New Generation and by Mars Colony Music in 2000 for 3rd Strike.
