==Call of Duty: Black Ops II ==
Engineer makes its debut appearance in Call of Duty: Black Ops II. It highlights enemy equipment including Guardians and Sentry Guns, which appear as flashing red through walls, delays proximity explosives such as Bouncing Betties, and adds the ability to re-roll, booby trap and defuse care packages. 
To re-roll a Care Package, double tap the Action button before capturing it. When an enemy Care Package is captured, either manually or through the Black Hat, it becomes booby trapped and will detonate upon opening. Packages booby trapped by enemies will glow in red, and can be defused without triggering the explosion.
Engineer goes well in conjunction with the Black Hat or EMP Grenade as it will assist detection of affectable technology, which include Sentry Guns, Guardians, player equipment, and most lethal equipment. The Black Hat can hack smaller equipment almost instantly through walls from a moderate range, making it perfect for players using this perk. It is additionally beneficial if a player has a Care Package selected as one of their scorestreaks and they call one in, as they can re-roll it for another scorestreak if desired.
