Top Gun Trivia
On June 30, 1988, Top Gun was put on the infamous German index by the BPjS. For more information about what this means and to see a list of games sharing the same fate, take a look here: BPjS/BPjM indexed games.
The original Spectrum version was incompatible with the +2A and +3 models. The Hit Squad reissue does work, but without the music.
