Dadam Game's Mystic Fighter Online lived a fairly short life shutting down months after it went live. The developers sincerely apologizes and will happily reimburse players that spent money on outfits excluding consumable items. I actually liked playing this game, but I guess most of the 2D Action MORPG community is busy with Dungeon Fighter, especially with the constant updates.

It's still unclear how this will affect the other versions of Mystic Fighter outside of South Korea. Developers sure have it hard in South Korea, given the amount of games constantly being pumped out and the competition.
