Banned In South Korea: Both versions of Ghost Recon 2 were previously banned due to a law forbidding games depicting war on the Korean peninsula. It has since lifted its ban on the series as a way of promoting freedom of speech.
Kozak in Future Soldier is voiced by Gene Farber - and when he's shouting while in combat, he manages to sound almost exactly like Grigori Weaver.
What Could Have Been: The build of Future Soldiershown at E3 2010 is almost nothing like the final game, featuring a completely different interface, level design and more overtly futuristic elements such as exoskeletons and shoulder-mounted rocket launchers. However, negative fan reception and Ubisoft's thinking that this version strayed too far from the rest of the series lead to it being scrapped and the game being revamped.
