A backpack-mounted graviton emitter that reduces the wearer's effective weight by up to 80%, enabling enormous leaps, controlled descent from heights, and movement speeds that appear superhuman. The GAMP-2 does not provide true flight — it reduces gravity's effect on the wearer rather than generating lift — but a person weighing effectively 20% of their normal mass can jump 5-story buildings, run along walls for short distances, and survive falls that would kill an unassisted person. The pack's graviton emitter draws enormous power and provides only 15 minutes of active weight reduction per charge cycle.
