9-11 Survivor was a mod for Unreal Tournament 2003, in which players were put in the shoes of the office workers in the World Trade Center towers on September 11th. Players were able to try and escape the tower after impact, although often the only options were to burn alive or jump from the building. The game caught a sizeable amount of flak from the media after its release, despite the creators asserting that, "9-11 Survivor is a game project that examines the role of media in our culture, and the influence that continuous, hyper exposure has on our overall perception of the distinctions between reality and media mediation." In fairness, the game was a lot more like a twisted art project than any kind of game, although the controversy was enough to make the mod the most downloaded for Unreal Tournament 2003 for quite some time. https://www.youtube.com/watch?v=c7WSCtV8A4w
