The Tomb Raider Level Editor (also known as winroomedit and commonly abbreviated TRLE) is a package of tools used to create game levels for Tomb Raider: The Last Revelation. Part of the package, the Room Editor, was used by the Core Design developers to create Tomb Raider levels. A version of the level editor was released to the public in 2000, as a second disc with Tomb Raider Chronicles (PC version only), that allows the user to create levels for Tomb Raider: The Last Revelation.
