With this in mind, the team at Ensemble created simple controls, consolidating similar actions -- such as different types of unit selection to presses of a single button. For example, single press of the A button will select one unit, a double click will select all units on screen, and a triple click will select the entire army. Another addition, all levels have been designed so that they can be completed without rotating the camera. Sure, players can rotate the camera, but they don't have to.
Finally, Devine mentions that there may be a level editor included with Halo Wars and also details Ensemble's plans for downloadable content. At the moment, new units and maps are definitely in the works. Even more exciting, Ensemble is considering releasing extra campaigns as well. Hit the "read" link for the full interview.
