Whether or not we see another Half-Life game after the excellent Half-Life: Alyx is entirely down to the capricious whims of Valve, but one thing we can be sure of is that it won't be in the form of Half-Life 2: Episode Three. For starters, simply too much time has passed for Valve to make another straightforward expansion to Half-Life 2. But there's also the fact Half-Life 2's writer, Marc Laidlaw, released his vision for the story of that elusive final episode.
That said, we might, just might, get to see Laidlaw's vision for Half-Life's concluding chapter in videogame form. Enter Infinite Finality, a new Half-Life 2 mod that is based upon the "Epistle 3" plot outline that Laidlaw released back in 2017.
