Online PC game publisher YNK Interactive (Seal Online) has announced 500,000 registered players for their MMORPG, Rohan: Blood Feud.

In open beta phase since May, Rohan: Blood Feud is free-to-play, and very much a traditional Korean MMORPG, though does feature some interesting twists, such as an emphasis on player vs. player combat, including a "hit list" for each player to remind them who killed them last and which allows them to warp to their location for revenge.

The developers place the growth in registration down to the features added to the game during the beta, including the game parlour (browser-based games which allow players to gain items for within the main game) and the exchange market, which allows players to buy and sell items to each other.

“I’m thrilled to have hit the half million mark, and still counting”, said Jun Lee, CEO of YNK Interactive. “As we continue to expand the game, so are we expanding our community base. We look forward to continuing to announce milestones like this in the months and years ahead.”
