The Necromancer leads an undead army to the fortress walls. A powerful artifact lies within the stronghold. A magical item imbued with immense energy. The Necromancer's powers are waning and his magical essence is fading with each passing moment. He will regain his powers if he manages to take the castle by storm and claim the artifact. So if the undead army manages to breach the fortress within eight turns, it will capture the artifact and achieve victory. If not... well, if not, the Necromancer's powers will fade away completely and the undead army will turn to dust.

Stronghold: Undead is a rebalance of the original Stronghold: Undead expansion for the second edition of Stronghold, which is now a standalone game. It features a new board with new paths to siege the castle, undead mechanics, and more ways for both sides to ensure their victory!
