The level editor is the internal tool originally used by Core Design, the Tomb Raider development team, to create levels for Tomb Raider. It was first included with the PC version of Tomb Raider: Chronicles in 2000, and later released for download with additional assets. Often referred to as "TRLE," it allows users to design levels using the Tomb Raider: The Last Revelation game engine. It comes with preloaded project files and their associated assets, including an exclusive original level and several sample levels from The Last Revelation. The accompanying manual guides users through recreating the exclusive level known as the "Playable Tutorial Level."
