[Source] As announced recently, Lunia Online Global will be shutting down on 1st January 2014, 24:00 (PST). For the past year or so, Korean developer All-M was operating the global English server based on donations from the gamers, and lack of funding is 1 of the core reasons for the closure.
As an observer, I must say Lunia Online did have a great run during its glory days, and living on donations is not really a feasible method. All-M will most likely continue to push its latest title, Kritika, for the overseas market, such as the all-important China region under Tencent.
