One of the most controversial video game missions of all time is "No Russian" from the 2009 version of Call of Duty: Modern Warfare 2. The horrific mission is disturbing enough that the game asks players right at the start if they are OK with viewing the content, or if they would rather skip it. In it, Call of Duty: Modern Warfare 2 players participate in a mass shooting at a Russian airport, mowing down defenseless civilians as part of a twisted false flag operation.
