Her Drive, Steins Gunner, summons a small orb at a set location depending on the direction used with the Drive button. Once these are out, you can begin your battle plan. The way you set up your Drives can mean life or death when it comes to Mu. You can choose to either fall back and lure your opponent in with your various assets (no, not those), or go charging in to lock them down with projectile mixup.
