It's a real intimidating factor when your playing against Sentinel players. This may be a little on the lame side, but hey, at least I can do it now. Being that I'm right handed, I find it much easier to have Cable on the left and Sentinel on the right. Then once this is done, I'll drop the Analog controller, push block and PRESTO!.AHVB inside HSF. So the actual HSF is done with my right hand index and middle finger and left hand thumb doing the half circle. How I do it is.with my left hand middle finger, I hold back on my Hori (Green Goblin).Of course, standing up Never crouching.during this time, I have my left hand thumb on the left Analog Control Stick (no vibration setting).then with my right hand middle finger, I tap the green triangle (beam) followed by the blue 'X' and red 'O' into HSF.
However, since I'm right handed, I find it easier this way. NOTE 2 Button configurations (Square = Light Punch, Triangle = Heavy Punch, X = Light Kick, Circle = Heavy Kick) Variations can change.One Hori Real Arcade Joystick ('Green Goblin' - my favorite since I live here in Japan) or Joystick of your choice.
