An ITV documentary screened last night presented footage from Arma 2 as a secret IRA film from 1988.
The clip, which you can see below (via PC Gamer), allegedly showed a helicopter being shot down by the IRA using weapons supplied by Colonel Gaddafi.
Speaking over the footage, the narrator says: "With Gaddafi's heavy machine guns, it was possible to shoot down a helicopter, as the terrorists' own footage of 1988 shows."
Responding to the programme, Marek Spanel, CEO of Arma developer Bohemia Interactive, told PC Gamer the company hadn't been approached by ITV about using the footage.
"We are going to try to get some explanation from ITV how this could have happened," he said.
"Sometimes creativity and realism in our games lead into crazy results and this is one of such example. I just briefly watched the entire documentary and I still can not believe it as it is overall very serious and lengthy feature.
"We are surprised our games apparently may look real enough to some users already that they can not tell it is not real life footage."
