Firaxis Games, known for the Civilization series and last year's strategy hit XCOM: Enemy Unknown, invites players to the Haunted Hollow this spring on iOS. Haunted Hollow is a free-to-play game (and we're already scared), where players rule a haunted mansion spawning creatures of the night they send forth to bother townsfolk.

The game features a single-player mode, along with multiplayer through Game Center or "pass and play." We'll have to wait and see how scary the microtransactions are going to be.
