Artificial Gravity
Yet another offshoot of Higgs field technology, where a Higgs field in tractor mode is used over a large area. In a pinch, and under unusual circumstances, a particularly creative agent can manage to use artificial gravity as a weapon, something akin to a broad tractor beam; since it can be scaled, a wily agent might run up the gravity in one room of a spacecraft while running it down in another. The resulting gradient is extremely difficult to traverse without injury.
