A game from Atari in 1980 which had a very  
      unique and special arcade cabinet
      two versions of the arcade came out one of which you stood on a step and peered through 
      some periscope style device to play the game. Its possibly the first 
      ever 3D vector game that came out.
Being a fan of the original machine we paid homage to it by building this 
      one off machine.
      it took 4 months to design and build with an update on the artwork to 
      match the look of the game more than the original artwork did.
      Complete 3D screen surround, two sheets of glass at different angles to 
      give the 3D effect depth 
      The control panel is fitted with two dual trigger joysticks and  6 
      buttons each.
