Hyper Street Fighter Alpha was an additional mode included in Street Fighter Alpha Anthology on the PS2. It included ‘Street Fighter 3-ISM’ mode that allowed characters to parry. There were other ISMs that gave the characters some new moves, such as Ken’s air fireball and Guy’s teleport. I’ve tried to include a bunch of them here.
