Society of the Serpent Moon is the fourth game of the series. Unlike the three first games, that had a first-person view, it implemented a third-person perspective, so you can see the protagonist. The story involves a missing girl, Wendy, fianceé of the protagonist of the game, Billy. Following the few clues her sudden disappearance left, Billy is involved in a dark and gloomy new world with fantastical creatures. The game is fully voiced and the player can hear Billy comments by clicking on "irrelevant" objects on the scenery. If you like the previous games of the series or horror-themed adventures, this game might be for you.

Not the best I've seen in my life, but it's an interesting game at least. The graphics aren't great, but they don't need to be. The sound is ok, and the gameplay is ok too. But where this game is great is on its storyline. It's very good. I didn't expect it to be so good. I even think ths is an underrated game. If you love story-driven games this is for you.
