You couldn't make stuff like up like this if you wanted to (and do you really want to do that?) but unfortunately it's totally real and currently doing the rounds with the more militant Mujahideen groups to boost morale and help recruit a new generation of young recruits.
The mocked-up Grand Theft Auto-style trailer is designed to attract younger members and features virtual fighters shouting "Allahu Akbar!" as they attack U.S. troops. According to Islamic State's media wing, the video aims to “raise the morale of the mujahedin and to train children and youth how to battle the West and to strike terror into the hearts of those who oppose the Islamic State".
The video trailer begins with a still image of a man with a covered head and face holding a weapon, with the words "Grand Theft Auto" printed over an image of a black flag featuring the terror group's logo. The gameplay features people pulling a police officer out of a cop car and shooting him to death, an explosive attack on a military convoy, a man hiding in trees shooting soldiers from a distance with a sniper rifle and the dusk attack of a convoy by men with assault rifles.
The words “Flames of War” appear at the end of the trailer, with the tagline: “Fighting has just begun”. Suddenly your favorite game has taken over a very sinister fan-made(?) fanatical overtone. Be afraid.
