The GA received a new kind of shield as a gift from yet unknown people. At first it was thought that the whole thing was either a joke or a trap, but after series of experiments on the shield the scientists found out that it was far better than the previous energy shields they had used, but like with all received technology there was a lot of compatibility problems, which need to be solved before this new shield can be installed on the GA ships.
It's believed that the so-called "T-Race Resistance" gave this new shield, but once again no confirmation is available as of yet. T-Race Federation on the other hand has grown more and more hostile towards every race in the galaxy. There's also been going on a wild rumor that the T-Race ambassador is part of this T-Race Resistance.
