UNDEAD: WHAT LIES BENEATH: Venture down many levels below this research facility and you’ll find the experiments dwelling there are growing restless.  Despite all knowledge gained while conducting their research, the scientists have forgotten one important detail...you cannot simply kill the Undead.

FERAL MOON: Take a walk through the town of Blackmoor and it’s crumbling, cursed cemetery. Beware of tonight’s full moon; it is said that werewolves will once again ravage the town after 100 years of containment. A modern interpretation of a classic monster of old...Feral Moon!
