It might not have the persistence of Hellgate: London, but Dungeon Striker has released and been shut down once before. Alas, its second lease on life was no more successful than the first, and the game will be shutting down in Korea again on February 11th.
Players can get a refund on some cash shop items, and anyone who had reached level 50 will be able to get a leveled-up Dragon Nest character for free. That may not make up for the sting of losing a game, but it can take the edge off.
