Hardcore Gamer: The SHMUP scene isn't just dominated by the big companies. MOSS, CAVE and Triangle Service aren't the only heavy hitters within the niche shoot'em up community. In fact, shooters have a huge doujin following. While some (read: many, if not most) are merely displays of amateur game development, others are handled with finesse and care, and led by big names within the scene. Enter Yotsubane, a one-man doujin developer best known for his, thus far, one and only vertical scrolling SHMUP, Crimzon Clover.
