More alien stuff? Nanoscreens. Nanofields (personal field providing Saturation Zone protection against incoming fire, someone came up with the idea in the new skills thread). Unique Perimeter Weapons (E/M? Viral? Sepsitor?). Functional Morpho-Scan. Mines with TO Camo, though this one might be too nasty. Shas mutations of Gakis and Pretas (Mimetism and Protheion, for example).
