Half-Life 2: Episode Three Mod Slated For "Late 2026"

Lead writer Marc Laidlaw left Valve in 2016, and the very next year, he released Epistle 3, a short, legally-distinct "fanfic" about Gertie Fremont that served as a collection of ideas on how he might have resolved the Half-Life 2: Episode Two cliffhanger. Laidlaw has expressed regret over publishing the story, mainly due to the trouble it caused his former coworkers, but that hasn't stopped fans from trying to adapt his vague outline into a fully-fledged game.
