Ragnarok Online 2: The Gate of the World (Korean: 라그나로크 온라인 2: The Gate of the World; alternatively subtitled Epic of the Light) was a massively multiplayer online role-playing game created by Gravity Corp. of South Korea and is the sequel to Ragnarok Online. Most of the game's universe is based on Norse mythology. After entering a closed beta testing phase in 2006 and continuing through 2010 in Korean open beta testing, the game was reworked multiple times due to its poor initial reception. In July 2010 it was announced the entire game had been scrapped, and a new version, Ragnarok Online 2: Legend of the Second, would be developed in its stead. The new iteration of Ragnarok Online 2 returns to the systems and mechanics of the original Ragnarok Online while keeping the 3D engine.
