Hello Urban Assault community!
Sektor is a fan-made map editor for Microsoft Urban Assault (1998), designed to simplify the creation and modification of custom LDF levels for UA / OpenUA / UA Source.
The editor converts user-created map data into Urban Assault-compatible level files through a visual interface, making map creation significantly easier compared to manual text editing.
