Futuristic Mechanized Combat From the introduction: FrameTek is a unique set of mechanics for the d20 System set in a futuristic advanced battlefield. It requires the use of Player's Handbook (D&D 3e). ... FrameTek is designed to introduce large combat vehicles and the classes that drive them into an existing campaign or to provide a source for ongoing campaigns set in the far future. The emphasis in FrameTek is still on the pilots and not as much in the frames themselves.
