Like the first game in the series, Double Helix pushed the boundaries of depictions of gore and violence, and is considered more graphic and realistic than most in the first-person genre.
Based on criticisms of the original game, Raven Software developed Soldier of Fortune II to be a more 'realistic' game, with more modern tactical shooters like Operation Flashpoint: Cold War Crisis (2001) and Tom Clancy's Rainbow Six (1998) serving as inspirations, rather than Quake (1996). Once again, Raven hired John Mullins to act as a consultant on the game. It was developed using the id Tech 3 engine as opposed to the original's id Tech 2, and published in 2002. Soldier of Fortune II: Double Helix is a first-person shooter video game developed by Raven Software, the sequel to Soldier of Fortune.
