“The armor’s shell is a multilayer alloy of remarkable strength. We recently added a refractive coating to disperse incoming energy weapon attacks—to counter our new enemies.” She pointed inside the schematic. “Each battlesuit also has a gel-filled layer to regulate temperature; this layer can reactively change in density. Against the skin of the operator, there is a moisture-absorbing cloth suit, and biomonitors that constantly adjust the suit’s temperature and fit. There’s also an onboard computer that interfaces with your standard-issue neural implant.”

    “Most importantly,” Dr. Halsey said, “the armor’s inner structure is composed of a new reactive metal liquid crystal. It is amorphous, yet fractally scales and amplifies force. In simplified terms, the armor doubles the wearer’s strength, and enhances the reaction speed of a normal human by a factor of five.”
