Alyx Vance is a fictional character in Valve's 2004 first-person shooter computer game Half-Life 2, and its following episodes: Half-Life 2: Episode One and Half-Life 2: Episode Two. Alyx is portrayed as a young woman in her mid-twenties of Black/Asian descent, and is a prominent figure in the human resistance against the rule of the alien race called the Combine and their human representative, Dr. Breen. She is a close friend and ally of Gordon Freeman and is considered to be the primary heroine of the series. Alyx's character uses a modified version of real-life actress Jamil Mullen's face, and her voice is performed by Merle Dandridge.

Alyx is the daughter of Dr. Eli Vance. Her mother, Azian Vance, who is of Asian descent, can be seen in a family photograph appearing in the games but died during the Black Mesa incident (the event depicted in the first Half-Life game). Alyx was only a child when Gordon Freeman was employed at Black Mesa, but Freeman's stasis between the events of Half-Life and Half-Life 2 has erased most of the age gap between the two characters.

Alyx is a skilled hacker, adept at infiltrating Combine computer systems and reprogramming them. She also possesses a multi-purpose tool that uses an electric charge in order to bypass security system, open locked doors, and re-program rollermines and automated turrets to attack enemies. Alyx is proficient with firearms, in particular the automatic pistol she commonly carries. At certain points in the game, she also wields a shotgun and mans a stationary sniper rifle. In addition, she has some skill in unarmed combat and will occasionally wrestle off or kick headcrab zombies. Alyx is also very athletic, capable of effortlessly jumping down obstacles and climbing to the side of buildings.

Alyx is a generally friendly person, though she shows some hostility towards Dr. Judith Mossman due to her somewhat patronizing attitude, as well as Mossman's apparent interest in her father. The hostility abates at the end of Half-Life 2, when Dr. Mossman helps Alyx in escaping the Citadel. She also holds Breen responsible for her mother's death (when Breen mentions her mother, she spits on him and responds, "How dare you even mention her!"). Also, she appears to be somewhat playful, and caring in some cases.

Alyx Vance has not been a contender in any CBUB matches.
