'Grand Chase') is a free-to-play, two-dimensional side-scrolling MMORPG, developed by the South Korean company KOG Studios.

[3][4] In 2015, the original game ceased development and terminated its service worldwide, with the Korean server being the last to close.

A spin-off borrowing some characters and taking place in a parallel universe, KurtzPel, is currently under Steam early access.

KOG has also announced a relaunch of the game for personal computers in 2021, retitled Grand Chase Classic, which started in closed beta testing.

[7] The story was focused on the adventures of the Grand Chase, a group of heroes from the region of Bermesiah, who departed on a quest to chase down the evil queen Kaze'aze, a witch who used her magic powers to cause a civil war between Bermesiah's kingdoms of Serdin and Kanavan.

The players control of one of the members of the Grand Chase, and fights through dungeons and Kaze'aze minions to get stronger and track the evil queen.

From the very start, there were three main characters available: the knight Elesis, the magician Arme, and the elven archer Lire.

The player might freely switch among the characters they had unlocked before entering combat, each with their own specific equipment, abilities and experience level.

Higher levels improved statistics, granted access to better equipment, and unlocked more difficult dungeons.

The size of the player's inventory was limited, but could be increased by purchasing space with paid currency or through events.

There were three types of PVP combat in Grand Chase: Team Battles, Survival and Honor Guard.

Alongside the regular match types, players could choose special modifiers to make fights more interesting: Tag and Item Mode.

In July 2018, the game was released internationally and renamed Grand Chase: Dimensional Chaser in Japan and the Philippines.
