Anna - Extended Edition is a horror adventure game developed by Dreampainters. The game is set in the mountainous region of the Alps in Northern Italy and is inspired by the Alpine folklore. The player controls a man who lost his memory and has to solve puzzles to uncover the mystery of Anna, a woman he can vaguely remember. The Extended Edition is an improved version of the original game, with added features and improvements.

The gameplay of Anna - Extended Edition focuses on puzzle-solving and recalling dialogues to uncover the story. Unlike most adventure games, not all items the player can carry are useful, and the game does not highlight the important items. The Extended Edition introduces a new AI-controlled character called “The Wife Doll.” The game also has improved graphics and user interface, as well as additional locations.
