If you do manage to break through the Vibranium layer, please say how you did it, i know of a few ways, including just submerging it in antimatter for half an hour, or dropping 5 or 6 times it's size in dest on it, but if anyone finds another way, i'd love to hear it.
Should probably mention that the useful things are, 1 a Neutron bomb, 2 a Vibranium overloader, and 3 a DRAY dest spike. going from left to right. Also my name is an EMP if you put some battery in the corner. Should help you out a bit. Enjoy :D
