Webzen's Continent of the Ninth Seal, otherwise known as C9, hasn't made a lot of noise in the West as of yet. That may change after next week's E3, when the South Korean action MMO import will introduce a new class and strut its stuff via the championship finals of its PvP tournament. The new class is called the Witchblade, and E3 attendees will get some hands-on time with it as they battle the forces of evil in the game's Blenheim region.

Webzen is also showing off Arctic Combat, a new online FPS set on the frozen tundra of World War III.

What does this mean?

C9 will be showing off the Witch Blade, which most likely will be included in the upcoming Open Beta. ^^ They're also showing off Arctic Combat, which those from OnRPG that will be attending E3 will get a chance to try. ^^
