Shivan full race addon
Another race subspacing in from the FreeSpace universe is the Shivans, an ancient xenophobic race thats been roaming the universe for millinnia wiping out any race unlucky enough to be in the way. Why? Nobody knows and its unlikely anybody will ever know at this stage.
The Shivans do posses a scary technological advantage over the GTVA. When the GTVA thought that they had technological superiority over the Shivans in the last shivan war the Shivans responded with a hundred juggernaughts, each capable of near total annihilation of the GTVA. They shattered the GTVA fleet and punched through to a populated world which was being franticially being evacuated by the alliance. As the alliance was busy collapsing the subspace nodes out of the system the Shivans then collapsed the star, causing a supernova which decimated everything in the system. The GTVA survived, at a cost of most of their fleet and an inhabited system.
And now, you have full control of the Shivans devastating arsenal.
On the matter of balance, the ships of the FS universe are possibly a tad overpowered for a stock game so they are probably better paired off with either a custom race you have modified to match the sort of firepower the FS universe throws around or the GTVA, which is the other FS race available for download.
