About Grand Chase
Grand Chase was a free-to-play, two-dimensional side-scrolling MMORPG, developed by the South Korean company KOG Studios. Initially released in South Korea way back in 2003, it was released later in overseas.
Alternative names for Grand Chase included Three Young Heroes (Chinese: 3小俠), Eternal Adventures (Chinese: 永恆冒險), both used in Taiwan prior to its closure, as well as Rainbow Warriors (Chinese: 彩虹骑士) on the Mainland Chinese server.
In 2015, the game ceased development and terminated its service worldwide, with the Korean server being the last to close. As of 2021, all official Grand Chase servers have been shut down, although a number of fan sites are still active to this day. (Wikipedia)
