Alyx Vance is the deuteragonist of Half-Life 2 and its episodes, serving as Gordon's companion and Eli's beloved daughter. She is considered a vital ally and therefore will regenerate health overtime. She is one of the few NPCs that have weapon holster/unholster animations and the ability to use the Alyxgun. Her original Half-Life 2 appearance features few special abilities beyond her weapon, but in Half-Life 2: Episode One and Half-Life 2: Episode Two, she's literally a completely different NPC. She has more comments, can count enemies, can protect herself when she isn't being mobbed, and can perform Dynamic interactions. Use ai_goal_follow to get Alyx to follow the player.
