The Jihadist group has released a video game trailer.
It is thought to be a way to try and recruit young fighters.
During the game, the virtual fighters are heard to shout "Allahu Akbar" as they attack US troops.
Islamic states media wing has stated that the video aims to raise the morale of the mujahedin and to train children how to battle the West and strike terror into the hearts of those who are opposed to the Islamic state.
The game includes the title of Grand Theft Auto shown over an Islamic State flag.
The game includes footage of explosive attacks on a military convoy and a sniper shooting soldiers.
