The Luyten Civil War is a user-made campaign for FreeSpace 2. From a narrative perspective, LCW is a traditional military campaign, with more emphasis on combat and politics than character development. The first version of the campaign is available.
This is the patched version of the June 15 release. It is a full download, and the changes to v1.0 are minimal, so if you have v1.0, you probably don't desperately need this patch.
