This is a genuinely rare cartridge for the C64, it never received a tape or disc release. Based on the 3rd movie depicting scenes as levels. First level is an average Op Wolf first person shoot em up but the remaining levels are the side scrolling shoot em up type. Not a bad game really, I personally prefer the first 2 games in the series though.
There have only been 2 copies of this in the last year and a bit listed on eBay, first went for just over 80 pounds and the second went for around 115 pounds.
