Stronghold : Undead

From the publisher's website:

This expansion for Stronghold introduces a new story about invading a castle – this time brave defenders have to stand against the forces of undead. Glory no longer matters – now both opponents fight for time.

The Necromancer has 8 rounds to defeat the men, or his army will vanish in the sun. Since after the 5th round his power starts to dissipate, he must pay to keep his forces still able to fight. If he can’t pay, the defender will earn more time to prepare for the battle.

Defenders die on walls. The necromancer’s power wanes. Who will be standing at dawn?

This expansion introduces a new set of buildings in the castle, a new set of Invader cards (24 new actions!), new rules (Fear level, Leader board) and much more.
