In the shadows of London, terrors stir. Powerful overlords conspire against one another, amassing hordes of monsters to do their bidding. Only one will claim the night and all within it as their prize. Terrors of London is a competitive deck-builder with a Victorian horror theme. Each player will assume the role of an Overlord, each with a unique ability and two unique influence cards. Throughout the game players will add monsters from four different factions (Beasts, Mortals, Spirits, and Undead) to their deck, all of which can form hordes for powerful combos. Players will also procure marvelous relics, which they may immediately use for their unique abilities. The first player to reduce their opponent`s life to zero wins the game and claims the night.
