Developer Firaxis Games is continuing to stay busy. After the success of XCOM: Enemy Unknown and the recent announcement of a new expansion for Civilization 5, the studio known is also working on a new free-to-play title for iOS called Haunted Hollow.

The turn-based strategy horror game, which offers single-player and multiplayer modes, puts you in the role of master of a haunted mansion where you spawn monsters to scare townspeople and try to gain control of a town. You'll be able to build the mansion and populate it with vampires, zombies, mummies, witches, and reapers. You'll be able to enhance all of your ghouls and bests with various powers and enhancements, as well.

Being a free-to-play game, of course, there will be things for you to buy in the game. According to Polygon, you'll be able to buy additional monsters for money. Haunted Hollow will be available on the App Store later this spring.
