Firaxis' Haunted Hollow is now available for free from the App Store.

The spooky strategy game sees players build and rule a mysterious mansion, spawning monsters such as vampires and zombies to unleash into the town. These minions battle with rivals to capture townhouses, fight enemies, avoid angry mobs and seize control of the town.
