Turok Evolution Engine

Not entirely sure if this engine has another name or not, but it appears to have been developed during Vexx's and Turok Evolution's development, with the latter being the first game released utilising it.

Supported the Nintendo GameCube, Sony PlayStation 2, Microsoft Xbox and Microsoft Windows.
