Instructor: Typically led by a senior level designer from a major game studio (e.g., Nexon, Krafton, or an indie hit studio). Coloso courses often feature Korean industry veterans with English subtitles.
If you commit to building alongside the lessons, you will finish with a portfolio piece that looks less like a student project and more like a junior designer's reel. Free YouTube playlists on whiteboxing (e.g., Steve Lee's "Level Design Workshop") + a monthly Unreal/Unity subscription.
Aspiring level designers, game design students, indie developers, or 2D/3D artists looking to transition into layout and environmental storytelling.
