Street Fighter III: Double Impact is a compilation containing the original Street Fighter III and 2nd Impact. It features an Arcade Versus Training and Option Mode for both games and a Parry Attack Mode in 2nd Impact where the player gets to test his parrying skills in the game's bonus round. This compilation also allows players to use Gill and Shin Akuma (in 2nd Impact only) who were exclusively computer-controlled characters in the arcade version.
