The guys at World of Spectrum have just worked with Dean Hickingbottom to recover remains of a rather neat little game called Ninja Grannies which was developed by Clockwise Developments. Well, its a one on one beat-em-up which isnt Street Fighter 2, but its quite a comical little game.
Unfortunately no publishers wanted the game, and so it remained unpublished. Spectrum and CPC versions were developed in parallel, and its believed a C64 version was also in development (Of which an entry exists on GTW64). Hopefully other versions will follow through in the future.
Grab it here, and enjoy!
