MU Legend is the hack and slash MMORPG developed by Webzen.

It is the official follow-up game to MU Online: one of the first 3D MMORPG in South Korea.

I participated in this project as a level designer intern for 2 months. (University summer vacation internship 2015)
The main task was dungeon encounter design in MU Legend.
I worked on deploying monsters and traps in 20+ dungeons based on the concept and balance of the game.
(The video posted below is a gameplay of the dungeon that I worked on.)
Plus, internship members including me analyzed total level design in beta test build and gave feedback to the game design team.
