This is Ghosts 'N Goblins online, by Korean developer Seed 9. It's coming to South Korea in 2011. Yay for South Korea, but what about the rest of the world?

We've contacted publisher Capcom to find out if this game has any chance of being released outside of South Korea and will let you know if they're able to comment.
