This is a great game from the nineties. The story is wonderful, told through chapter intros and closings. The game play is lots of fun. Medium difficulty is really hard. Try it on easy first and then graduate to medium to avoid frustration and don't forget to reload that Colt 45 or you will die. The extra missions are a lot of fun too. Remember, it is a game from the almost twenty years ago based on a modified Dark Forces engine, so it is not going to look like today's games, but its great. As others have said the music is original but sounds as though Ennio Morricone wrote it himself. I have had this game on disc for years but it has been extremely difficult to get running properly on a modern pc. Thank you so much GOG.
