Zombie Posted January 15, 2017 Report Share Posted January 15, 2017 UFO Research Tree. Fusion Ball Defenses require (obviously) the Blaster Launcher + Blaster Bomb and then the Fusion Ball Launcher. As for the Grav Shield, you'll need to have Alien Alloys + Elerium 115 + UFO Navigation + UFO Power Source. Those lead to UFO Construction, Firestorm and Lightning which will then open up Grav Shield. - Zombie Link to comment Share on other sites More sharing options...
