- "Obsessed with numbers and calculations, only living by the rules discovered by great mathematicians, the Engineer never attacks his targets without careful preparation. Accompanying him from plans to action, his Compass has pierced more skulls than sheets of paper."
- ―Ubisoft description.
The Engineer (real name: Gaspar de la Croix) was an Animi Avatar used by Abstergo Industries, to train the recruits in the first stage of their Animi Training Program. His assassination weapon of choice was a drafting compass.
The Engineer had several unique moves:
(Low Profile, Front)
The Engineer casually approaches his target, before grabbing them by the back of their head with one hand and pushing the sharp points of his compass through the soft flesh underneath the jaw and the inside of their skull, piercing their brain. He then removes his compass and stores it back into a pocket on his satchel, while his victim's dead body falls to the floor.
(Low Profile, Back)
The Engineer walks up to target from behind and kicks their legs out from underneath them, so that they fall to their knees. He then grabs his compass by its handle and stabs them one-handedly in the top of their head, puncturing the brain, while keeping them steady by holding their shoulder with his other hand. Removing his grip on his victim, he lets their body fall forward to the ground, while blood spurts out of their wound.
(High Profile, Back)
The Engineer quickly comes up from behind and grabs the back of his target's waist, before forcefully pulling themm backwards and stepping forward himself. With his compass in his hand and the momentum of his pull, he jams his weapon into their back, impaling one of their kidneys on the compass' sharp points. Letting go of his victim, the Engineer conceals his weapon while he watches them collapse to the ground, where they would bleed to death internally.
(High Profile, Front)
The Engineer walks up to his target from the front and reaches around their head, grabbing them by the scruff of the neck. He then yanks their head downward and delivers a quick but fatal stab to the crevice of the shoulder blades, before letting go and watching his victim fall forward to their demise.
The Engineer walks up to his seated target and grabs the side of their head with one of his hands. He then takes his compass in his free hand and forcefully thrusts it into their neck, piercing their jugular, before pulling his weapon away and concealing it, as his victim's dead body slides from the bench.
The Engineer jumps from above a rooftop onto his target and pulls out his compass, before brutally stabbing them in the back of their head. Leaving his victim to die from the wounds he had inflicted, the Engineer stands up and stores his compass back into his satchel.
