In 2015, Fantasy Flight Games released the Nightmare Deck "Assault on Osgiliath", an expansion that brings the epic Osgiliath setting into the cooperative universe of The Lord of the Rings: The Card Game. The goal is simple yet challenging: players, led by Lord Boromir, must conquer and maintain control of all Osgiliath locations before the Enemy destroys the city. Each game requires careful hand management, strategic use of encounter cards, and constant adaptation to power shifts as more locations are taken. Nightmare Mode ramps up the tension: enemies and treachery cards grow stronger as players progress, demanding quick decisions and tight collaboration. Additionally, the deck introduces new encounter cards and instructions on reshaping the original deck, letting fans experiment with unpredictable variations of the classic scenario. Variable Player Powers ensure each participant has a unique ability, making every session distinct. The expansion includes 150 cards, new scenario, enemy, and action cards, plus game components such as location tokens and damage markers. It runs in 30 to 90 minutes and supports 1 to 2 players, ideal for groups seeking intense cooperative play without a large group. If you’re familiar with the LCG series and want to test your limits against the Enemy in a darker setting, "Assault on Osgiliath" is a pick that will keep you on the edge of your seat. Get ready to march, face challenges, and experience an epic battle in the heart of Osgiliath.
