CSO 韓國8月10日更新：楓之谷地圖遊玩 South Korea 8 10 Updates Maple Story Theme Map Gameplay

Trivia

The dialogue from the CSO Comics #1 to #3 is lifted from the rather infamous Doom comic, as stated in the map description.
This mode is likely to be influenced by a popular sandbox game, Garry's Mod.
Unlike Valve Hammer Editor, this mode does not support curve splicing. Objects in it are in larger ratios.
This mode is similar to an open source game, Cube and Cube 2: Sauerbraten with the Edit mode.
Studio Mode has been in development since the start of 2016. As a result, updates slowed down in 2016 up until its release in 2017. The only new mode that was added during this time was Playroom.
