Call Of Duty : Modern Warfare 2
The EMP' (ElectroMagnetic Pulse) is an unlockable killstreak reward in Call of Duty: Modern Warfare 2. Requiring a killstreak of 15, or occasionally found inside a Care Package, the EMP disables all enemy electronics. Hostile players will have no HUD, and electronic scopes (such as the Red Dot Sight) will be disabled. Their vision will also be slightly fuzzy. Any enemy sentry guns will be destroyed and all hostile aircraft will crash. Enemy players will be unable to activate their own killstreaks while they are affected by an EMP. The EMP effects last for 60 seconds, but does not affect friendlies.
