Origins
The first Soldier of Fortune, released in 2000, was named after the American magazine and built on the Quake II engine. Its player character was based on John Mullins, a real former US Army Special Forces soldier who worked with Raven as a consultant. The game became known for its realism and its very graphic damage system, which caused controversy at the time.
Soldier of Fortune II followed in 2002, moving to the more advanced Quake III engine. Its single-player campaign follows Mullins through a story about a biological weapon, which gives the game its “Double Helix” subtitle.
What made it stand out
- GHOUL 2: Raven’s model system divides each character into many separate damage zones, so where a shot lands decides what it does. It also allowed far more realistic-looking characters than most games of the time.
- Real weapons: 20 multiplayer weapons and grenades modelled on real firearms, from the M4 and AK-74 to the MSG90A1 sniper rifle. See SoF2 weapons.
- Round-based objective play: Infiltration and Elimination made careful team play matter more than fast respawns, a style that kept clans playing for years.
- Random Map Generator: SoF2 could build outdoor terrain maps automatically, a rare feature in 2002.
- Built-in anti-cheat: the game shipped with PunkBuster support, now switched off because the service no longer runs.
The multiplayer years
Through the early 2000s SoF2 had a large online scene of public servers, clans, ladders and leagues. Version 1.03, released as part of the Gold Edition, became the standard most servers ran. Raven released the multiplayer game code for modders, which led to mods such as RoCmod, OSP and later 1fx. Mod. Community websites, including the long-running SoFPlayers.co.uk, kept players connected.
How SoF2 survived
Like many games of its age, SoF2 lost its official master server, which filled the in-game server list. Without it, new players saw an empty browser and assumed the game was dead.
The community responded. The 1fx. team built a client patch that points the game at a community master server and fixes crashes on modern graphics cards (see 1fx.). The Gold Edition came to GOG.com, making the game easy to buy again. Server owners kept servers running, and sites like SOF2MP.com began tracking every server and player to show that people still play.
