Here is a repository for some of my custom content for FreeSpace 2. My FreeSpace days are more or less over due to wandering interests and accompanying time constraints although I hope to return in some capacity some day.
This is a modified version of the main FreeSpace 2 campaign for multiplayer. Somebody else did the initial conversion and all I did was fix some outstanding issues, like in some of the SOC missions. I believe it is available in one of the larger mission packs somewhere on HLP.
