Elsword is a free-to-play, two-dimensional side-scrolling MMORPG by the South Korean KOG Studios.

Originally, Elsword was a reboot of the MMORPG Grand Chase, also developed by KOG Studios. Many of Elsword's game elements are similar to those of Grand Chase, such as the characters Elsa, Aisha and Rena, as well as the skill system, character stories and monsters.
