Clint Hocking is the creative director for Far Cry 2 and he recently did an interview (https://www.ign.com/articles/far-cry-2-fan-theroy-the-jackal-is-jack-carver) for an IGN documentary about the villains in the Far Cry series. He confirmed a theory about the villain in Far Cry 2 that fans had speculated about for years.
Hocking confirmed that the Jackal from Far Cry 2 is the protagonist from the first game. This has been a popular fan theory despite there being no information in the game to suggest this was the case. According to Hocking, the Jackal is just Jack Carver 10 years in the future who for some reason has “levelled up his smuggling game”. He didn’t give a specific reason for this but did speculate it may have been due to drugs or post-traumatic stress disorder.
“Jack Carver in the original Far Cry was this shifty, smuggler, gun runner kind of crook,” Hocking explained. “The idea was [the Jackal] is just him, 10 years later or something, after he’s seen whatever he saw on this island [during the events of Far Cry]. Maybe it was drug induced, maybe it’s post-traumatic stress disorder, or maybe it’s real. But the idea is, a decade later, he has levelled up his smuggling game, and he’s gotten embroiled in this conflict.”Clint Hocking
The credible theory was also fuelled by all of The Jackal’s texture files having “jackcarver” in their names. The two characters have also always had similar backstories.
