Unbeknownst to me at the time, the totally banging title screen music from this great game was a YMO song called "Rydeen". I often thought the 45 degree slanted buildings and towers was very 80's Tokyo. The marquee at the top announced how many pizzas, chips, burgers, crisps and cans of coke the makers had devoured whilst making the game. This was a very special game, very tough, very original in format and style and almost epic degrees of timing were needed to complete the enhanced BBC Master version, as I found out years later when I completed it with save states on an emulator like a full-force dweeb. It featured totally mind-blowing graphics for British micro-computer children of the 80's: guns, grenades, mines, machine guns, helicopters of varying size and even slick knightriderish space shuttle bombers - wow!
