The Serious Editor is a series of programs developed by Croteam for creating and modifying content for the various versions of the Serious Engine.


The Serious Editor are tools used by Croteam for editing and creating content in the various Serious Engine versions. Some of the features seen in various versions of the Serious Editor include a level editor, importing and exporting textures, and importing models to be used in various Serious Engine games.

Originally, the primary tool in the Serious Editor is a level editor that lets people create new ones and edit existing ones. However, other tools have been added for creating, editing and importing content, giving the user more control over creating and editing content.

All major versions of the Serious Editor have been made available to the public in one way or another. Some have been included with the game (Serious Editor 1, the Serious Sam 3: BFE version of Serious Editor 3) or added later on (like Serious Editor 2).
