The campaign won't have a linear structure either; rather than play through a predictably linear series of missions that become more difficult over time, War of the Ring's campaign will progressively unlock small groups of missions and let you choose which ones you'd like to play next. The order in which you unlock the campaigns won't be strictly linear, but will instead be governed by the chronology of events in Tolkien's fiction. Each of these missions will include introductory and closing cinematics, as well as an epilogue that explains the significance of the mission in the struggle for power between the forces of good and evil within the time line of Tolkien's third age. Many of these missions will feature multiple objectives and side-quests that can be performed in exchange for miscellaneous benefits.
