Deus Ex: Human Revolution
Yelena first appears in Deus Ex: Human Revolution at the beginning of the game. Yelena along with Lawrence Barrett, Namir, and a small company of assisting augmented black ops soldiers, all stormed and destroyed the Sarif Industries headquarters in Detroit, Michigan and destroyed all of their research of augmentations and advanced human evolution. Yelena is first seen where she breaks into a room and guns down a small group of scientists and eventually leaves after Jaron shoots Jensen and kidnaps Megan Reed.
Six months later and Adam Jensen is back in action and seeking revenge. Yelena appears at the Highland Park FEMA Camp Facility after the Tyrants members regroup at the facility after she and Barret failed to retrieve the Neural Hub from a member of the Purity First terrorist organization but Jensen got to it first.. Yelena is with Namir entering into an elevator when Jensen arrives. Barret grabs him and throws him across the room as Yelena and Namir both escape and leave Barret to Jensen but Jensen wins and kills him. Eventually, Yelena confronts and fights Jensen at Eliza Cassan's AI Facility and although she's a skilled fighter, she gets beaten and is left severely wounded. Her status is left unknown after her fight with Jensen.
Yelena is a tall, slick, Afro-Russian women and is very young considering her birth date was in 2001. Yelena has many augmentations on her body and she's most notable features are her legs which are taller and more thin than an average persons. She has a nose ring piercing and has black greasy hair combed to the right side of her head.
Yelena notably never speaks a single word through out her short amount of screen time, making her a silent but deadly foe. She witnessed the brutal death of her entire family and as a result she is scared and most likely holds back many negative emotions to prevent a total break down. Like all Tyrants members, she is loyal to Jaron Namir and follows his every command.
