History of Upgraded Sensor Pack

Upgraded Sensor Pack is the Exotic intrinsic perk of Knucklehead Radar. It keeps radar visible while aiming, improves radar resolution while crouched, marks targets, increases damage against marked targets at low health, and provides a small airborne-effectiveness bonus to all weapons. The current description is broader than the perk’s 2017 radar-only wording, so the older description should not be treated as the complete current effect.
