The leaked images – which originate from an “anonymous Valve source” – show new enemies, redesigned Combine costumes and some of the general detail in the world of City 17.
“These are not screenshots that were cherrypicked directly by Valve to best illustrate the game,” explained VNN. “These are screenshots taken by a person who has access to the game at random.”
The game, which Valve insists is not a spin-off but “the next part” of the story, can be pre-purchased for $59.99 and is free for owners of the Valve Index VR headset or Index controllers.
Set between the events of Half-Life and Half-Life 2, the game sees protagonist Alyx Vance and her father Eli secretly mount a resistance to the occupation of Earth by a mysterious alien race known as The Combine.
Valve says Half-Life: Alyx was “designed from the ground up” for Virtual Reality and “features all of the hallmarks of a classic Half-Life game,” including “world exploration, puzzle solving, visceral combat, and an intricately woven story that connects it all with the characters iconic to the Half-Life universe.”
