Alone in the Dark: The Trilogy is a compilation that brings together the first three entries in the Alone in the Dark series. Originally released in the early 1990s, these games are considered foundational to the survival horror genre. The trilogy follows investigative characters who confront supernatural threats through exploration, puzzle-solving, and limited combat. It features early use of 3D character models over pre-rendered backgrounds, a technical hallmark of its time. The collection preserves the original gameplay and presentation, reflecting the design conventions and limitations of early PC horror games.
