Most Soldier of Fortune II players only need RoCmod, because most public servers run it. Install OSP if you play clan matches on OSP servers, and 1fx. Mod if you play Hide & Seek or Humans & Zombies (many 1fx. servers need no download at all). Mods sit in their own folder next to base, and the game loads the right one when you join a server.
What a SoF2 mod is
A SoF2 multiplayer mod replaces the game’s rules code on the server, and often adds matching files for players. Mods add admin tools, new game modes, statistics, match controls and fixes, while the maps, weapons and engine stay the same. Mods exist because Raven Software released the code for the multiplayer game rules so the community could build on it.

How to install any SoF2 mod
- Download the mod for your game version from our Mods page.
- Extract the zip into your SoF2 folder, the one containing
SoF2MP.exe. - Check the mod’s folder sits next to
base, not inside it. Don’t rename it: servers expect the exact folder name. - Join a server running the mod. The game switches to it automatically.
Soldier of Fortune II/
├─ SoF2MP.exe
├─ base/ ← maps go here
├─ rocmod/ ← mods go here,
└─ osp/ ← next to baseTo start the game straight into a mod, add +set fs_game rocmod (with the mod’s folder name) to the end of your shortcut’s Target box.
Maps and mods
Keep maps in base, never in a mod folder. Maps in base work with every mod. Maps in a mod folder only load with that mod.
Common problems
- “Mod not found” or kicked when joining: you don’t have the server’s mod, or you have a different version of it. Download the version the server names.
- Settings missing in a mod: each mod keeps its own config in its folder. Copy your binds into it, or use an
autoexec.cfgin each folder (see best settings). - Mixed versions: a v1.03 mod won’t load in v1.00, and the other way round. See versions explained.
Frequently asked questions
What’s the most popular SoF2 mod?
RoCmod. Most public servers, including -=[L!VE]=- SOF2MP.COM, run it.
Can I have several mods installed?
Yes. Each mod has its own folder, and the game loads whichever one the server you join is running.
Do I need a mod to play?
Not for servers running the plain game, but most servers run a mod, so installing RoCmod lets you join the most servers.
