Remarkably, the most exciting mission is one that doesn’t involve any building at all, and that’s the defense of Helm’s Deep – the one so vividly portrayed in the recent film. Helm’s Deep is like a series of gauntlets (yes, you do defend that little sewer grate that should really have no reason to exist) that tests your ability to maintain an ordered fighting battle strategy in multiple locations on the map. You’re given all the usual heroes -- Aragorn, Gimli, Legolas -- but they can’t all be at one location so as time counts down to the arrival of Gandalf and the minions of Saruman swarm in ever greater numbers, it’s up to you to multitask and manage your limited to resources to hold off the inevitable.
