The Bydo Shot is a basic projectile fired by the vast majority of Bydo. It's a red-orange bullet that travels at a decent velocity and usually travels faster with increased difficulty. In R-Type Command/Tactics, it's regularly used by Force devices. It can be fired at any vector and is primarily delivered by Cancer, aerial attack ships such as Pata-Pata and Crack, Blaster, Cannon, ground attack machines such as Bink, and most of the rest of the Bydo.
The Space Corps equivalent is the Vulcan Cannon, an energy weapon used by nearly every R-craft. Though the vulcan has a faster firing rate, it's limited to a forward-firing position and the projectile is a little smaller.
