Massive Darkness brings the classic fantasy RPG experience to modern board gaming. Players begin their adventure in Massive Darkness by picking a Hero and pair them with a Class of their choosing. The created Heroes go on Quests, killing monsters, collecting loot, and gaining XP. Players spend their XP to unlock new Skills, growing more powerful as the Quest progresses.
Throughout the game, players encounter different monsters, including Minions, Agents, Roaming Monsters, and Bosses. An unique mechanism of the game is the Guardian. Any of the monster types have a chance of spawning as a Guardian, meaning it will use a random piece of equipment in the fight against Heroes. However, if players are able to overcome this difficult encounter, they will acquire that piece of loot!
