Here is a great papercraft mech by Cantaris at the Mech3.org forum. I believe this papercraft was based on a 3D model from a video game, although I am not sure which one.(Anyone care to enlighten me? ^^) This mech's model type is called an "Awesome". It comes from the BattleTech universe which got its start in miniature gaming in the 80's and later came to include video games and an animated series. A download of the Pepakura PDO template (which includes a whopping 121 different skins!) is available here.
