The Splinter Cell News Page (thanks Frans) reveals that a map editor will be released soon for the PC edition of Splinter Cell: Pandora Tomorrow. The editor will be based on the Unreal editor, and along with its release will be the release of all the source maps from the game in editor format so they can be adapted, and perhaps more importantly, analyzed for the techniques they reveal. Also, Leakfree.org is dedicated to map and mod creation for Valve's just-released Half-Life 2, as well as other Source-engine games.
