This mod adds a new faction (DkR/Dark Reavers, the name of my gaming clan) to Sins of a Solar Empire: Rebellion and also enhances all weapon effects and sounds of the existing factions. The DkR faction was originally mechanically identical to the Advent Rebel faction, but has gradually become completely different.
1.4.x is the latest version of the mod which completes the transition from DkR being a reskinned Advent to being a completely distinct faction. All DkR ships now have unique abilities and the research trees are completely different to those of the other factions (aside from a borrowed Advent diplomacy tree as there's not a lot you can do with diplomacy). Updated to work with Sins v1.86.
