War of the Ring: Sieges of Middle-earth

From BoardGameGeek:

During the War of the Ring, the strongholds of the Free Peoples faced their darkest hour, under assault by the relentless armies of the Shadow. Siege towers advanced against mighty walls; catapults battered the defenders day after day. Yet these assaults - those that took place, and those that might have - were decided not only by swords and engines of war, but by the endurance and courage of the brave souls standing against overwhelming odds. Sieges Of Middle-Earth is the fourth expansion for the War of The Ring: Second Edition board game, focusing on the siege battles against the main strongholds of the Free Peoples. New game mechanisms bring those desperate battles to the forefront of the conflict: the Shadow player can field powerful siege engines to smash fortifications and spread despair among the defenders, while the Free Peoples player may attempt heroic feats, lead bold sorties, and inspire last stands that can turn the tide of battle. New components include plastic figures, special dice, tokens, and cards to add to the core game, expanding the strategic options of both players and enhancing storytelling possibilities. -description from the publisher
