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.
Isn't that a D'deridex class warbird?
It is indeed. Also my favourite ship design of all time. I explained the use of Romulan ships in the mod summary if you're wondering why.
