In this new video, desk discusses an interesting property that Street Fighter V shares with some specific versions of Super Street Fighter II: the ability to add a second projectile while there’s another already active. Aside from under certain conditions–like Guile’s V-trigger, or Ibuki’s multiple kunai–this isn’t something you’re able to do in the Street Fighter series.
Basically, when a projectile moves offscreen in Street Fighter V, it seems to lose its hitbox and other properties, even if the action shifts the viewable area of the stage back to where the projectile is still visible. Once the original projectile has been “nullified” this way, it’s possible to throw out another one–causing multiple projectiles to be visible at once, even if only one has a hitbox. Interestingly, Ibuki’s bomb is an exception and stays active, even if offscreen.
