Engineer
Tier 3 Perk
Unlocked at	Level 14

"Show enemy equipment in the world. Delay triggered explosives. Reroll and booby trap Care Packages."

— Create-A-Class Description.

Engineer is a Tier 3 perk featured in Call of Duty: Black Ops II. It is similar to the Hacker Perk from Call of Duty: Black Ops.

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.

StrategyEdit

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 reroll it for another scorestreak if desired.

Its ability to clearly identify obstacles can make it an effective alternative to Flak Jacket, helping the player avoid being killed by placed equipment. Engineer can also show where shock charges are placed, which a player with Flak Jacket is not protected against. However, a disadvantage is that with Engineer replacing Flak Jacket, the player is still vulnerable to explosive grenades and launchers, whereas Flak Jacket's added protection allows one to survive said threats.
