Description from the publisher:
In The Siege of Annuminas, the ravaging hordes of Angmar are marching on Annuminas, and it’s up to the players to defend the city in an adventure designed for 1-12 players. This unique scenario can be played in two different game modes: Standard Game Mode or Epic Multiplayer Mode. Standard Game Mode requires only 1 copy of The Siege of Annuminas and supports 1-4 players like every other The Lord of the Rings LCG scenario. But Epic Multiplayer Mode requires three copies of The Siege of Annuminas and supports 3-12 players!
