The Maelstrom Mod introduces four new races to the Sins of a Solar Empire Rebellion Universe. They are independent of the original races and have unique strengths and weaknesses. Maelstrom is available for Rebellion, Diplomacy, Entrenchment and Original Sins.
Amazing mod, there are some balancing issues certain races but absolutely amazing. The amount of planets you get in this mod and attention to detail on the units is amazing. Keep up the good work
