Soldier of Fortune: Payback

Soldier of Fortune: Payback is a first-person shooter video game and the third installment of the Soldier of Fortune game series. Unlike the previous two Soldier of Fortune games, which were developed by Raven Software utilizing the Quake 2 and Quake 3 engines, Payback was developed by Cauldron HQ, developed with Cauldron's in-house CloakNT engine, used in their previous first person shooter game, Chaser. It is the first game of the series released for the Xbox 360 and PlayStation 3. The game was released on 14 November 2007.

Soldier of Fortune II: Gold Edition is a two-CD set containing the original Soldier of Fortune II: Double Helix with enhanced gameplay and additions. Players take the role of mercenary John Mullins as he hunts down and eliminates bio-terrorists that are threatening the world with a deadly plague, the Gemini Virus. The Gold Edition contains more than 55 levels, eleven new maps, a new infiltration multiplayer game mode, an expanded arsenal including weapons such as the SIG 552 rifle, MP5SD, and Silver Talon pistol, and an anti-cheat "PunkBuster" modification. A single-player random mission generator promises diversity in gameplay and offers four mission types (escape, assassination, infiltration, and demolition), varied locations (desert, hills, jungle, plains, or snow), night or day settings, four difficulty levels, and time limit options. The original Quake III: Arena engine has been enhanced with GHOUL II technology that provides improved animation and more carnage with 36 damage and 16 dismemberment zones. Other features of the graphical upgrade include per-pixel hit detection, new facial animations and full skeletal soft-skinned models.

Soldier of Fortune II: Double Helix is a video game created by Raven Software, a sequel to Soldier of Fortune. It was developed using the Quake III: Team Arena engine. Once again, Raven hired John Mullins to act as a consultant on the game. Based on comments and criticisms of the original game, Raven Software developed Soldier of Fortune II to be a more "realistic" game, with tactical shooters like Operation Flashpoint: Cold War Crisis and Tom Clancy's Rainbow Six as inspirations rather than Quake. A sequel titled Soldier of Fortune: Payback, made by Cauldron HQ was released for Microsoft Windows, PlayStation 3 and Xbox 360 in 2007.
