Call Of Duty : Modern Warfare 2
Scrambler is a Tier 3 perk appearing in Call of Duty: Modern Warfare 2 that scrambles the radar of nearby enemies, leaving only static. Enemies that are close to, but not entirely within, the scrambling radius will have their radar appear slightly fuzzy and faded. The Pro version of this perk protects players from enemy Claymores by increasing the time between detection and detonation. The main way to tell the difference between a Counter-UAV and a Scrambler user, other than hearing the announcer alert the team of a Counter-UAV, as Scrambler causes the radar to fade gradually, depending on the distance between players, while a Counter-UAV cuts out the radar completely regardless of location. Scrambler is unlocked at level 17.
