Half-Life: Alyx // Chapter 11: Point Extraction

Inside the Vault, Alyx finds the remains of the building the Combine trapped within the Vault in order to capture their prisoner: however the building appears to defy reality itself, with numerous rooms being oriented differently and the objects within them defying the laws of gravity. Making her way into the main prison, Alyx discovers her gloves can absorb the Vortigaunt energy previously used to power the Vault and uses them to fight off the remaining Combine forces. Inside the Vault she finds a giant cage and frees the individual inside, only to find the prisoner was not Gordon but the mysterious G-Man.
The G-Man offers his services to Alyx in return for her releasing him, but when Alyx asks that he remove the Combine from Earth he turns her down, noting it would be against his employers' wishes. He then shows her a vision of the future: her father's death at the hands of an Advisor in the hangar at White Forest in five years' time. He then rewinds time to just before Eli's death and gives Alyx the chance to save her father. Alyx uses her gloves to destroy the Advisor and free Eli. However, the G-Man explains she has proven herself a worthy successor to Gordon Freeman, whom the G-Man is disappointed with for failing to follow through on his directions. Despite Alyx's pleas to let her go, he places her into stasis.
