"What the fuck is that?"

"EMP! Everyone hang on!"

-- Sangheili Marine and Major Josh Konaree

The EMP (Electro Magnetic Pulse) is an unlockable killstreak reward in Keros. 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 effects of an EMP last for 60 seconds, but does not affect friendlies.
