Greatest Killstreaks In Call of Duty

System Hack

If you are tired of your opponents jumping around you and killing you over and over again, then the system hack may be the option you want to go for. Once enabled, the system hack disables enemy radar and reticules, which basically means they are shooting blind, especially if they have reticules instead of iron sights. Additionally, and this is my favorite part, the System Hack can also be upgraded to disable enemy equipment, Exosuits and streaks.
