The Lord of the Rings Online: Helm's Deep is the fifth expansion for the MMORPG The Lord of the Rings Online. It was released on November 20, 2013, after it was postponed by two days from the original release date, due to a power outage. The expansion is available for download both on the web and on Steam. The Battle at Helm's Deep is created in-game using refined technologies that Turbine created during the development of the expansion, which allow for a significantly larger amount of action and character models during a session. The new expansion increases the in-games level cap to 95, and one of the main new features is the ability to fight "epic"-scale battles such as the Battle of Helm's Deep. The expansion also adds modified trait trees and five new zones to explore in Western Rohan.
