I semi-main Snake, somewhere in between an alt and a main. Whatever, not important. What is important is that I've seen the first hit of the F-tilt (knee) knock the opponent back in several situations. But it's supposed to just set up enough hitstun to allow the second, clubbing hit, right? So, what makes it sometimes have it's own knockback? Is it what part of the hitbox makes contact? whether or not the opponent is airborne? Does anyone know?
