Daum has announced via the Lime Odyssey Korean site, that the game will be closing for good in February 2014. MMO Culture has discovered that the closure is nebulously attributed to "financial woes".
It seems oddly strange as Cykan Entertainment, once known as Sirius Entertainment, managed to sign Lime Odyssey to various countries, including Taiwan, Thailand and North America. Daum also poured money to market the game locally. We might never know the real reason for the downfall.
It is assumed that the closure is effective in all locations though we have not seen any official word on the NA forum.
