Being familiar with both Heart of Darkness and Apocalypse Now, there were few surprises in the story. I do like it that they made your character lose his mind and put you in his version of reality. It was a bit startling to see what was actually going on later. I hadn't seen anything quite like that before in a game, at least not as well done. It also had several endings, which was rare in FPS games at the time. Overall, it wasn't anything special or unique in literature or movies, but it was something new for video games and introduced a new generation to a classic tale of madness and the horrors of war. I don't think it's worthy of any cult fandom, but it's definitely worth playing if you find it in a bargain bin somewhere. Especially if you're unfamiliar with the overarching plot.
