Description
Monster in the Mansion is an asymmetrical survival horror game set in the mansion of Doctor Mondo, a Victorian-era scientist who cracked travel between dimensions… and lost control of it. Now dimensional energy is bending space-time, twisting the mansion and transforming its residents into monsters. Eight friends enter to rescue them but one of their own was turned, now the rest must craft the antidote to save their friend before he turns them all into monsters, one by one. Most horror games are about escaping the monster. This one is about saving it!
