Valkyrie Sky: World’s First MMORPG Shoot ‘Em Up?

Valkyrie Sky is pretty much what happens when you introduce the MMORPG genre to something as alien as the SHMUP style. In Valkyrie Sky, players can choose between four unique character classes (these classes can then sub-specialize into four+ additional subclasses like Knights, Warriors, Protectors, etc), to smash through levels and bosses in a SHMUP style of gameplay. What makes Valkyrie Sky so unique, however, is that the world players enter is meant to support an MMO community, and you can play with up to four players in PvP (odd, yes) or to tackle more difficult dungeons.
