Sins of a Solar Empire: Rebellion Mod - Enhanced 4X v1.72

Combat will still be the center point of the game, but players will find that the non-combat options available will be much more rewarding. Spying, exploring, sabotage, diplomacy, culture, and economic development have all been added or changed in innovative new ways. Regardless of what you think Sins is, this is the 4XRTS it should have been.
