We played through an early version of one of the game's first few levels, which takes place in and around a London subway station that has been converted to a makeshift templar camp. In the game, you'll meet non-player characters (NPCs) who can give you quests to perform, buy and sell items, and even appear as civilians on the battlefield who must be rescued and escorted to safehouses. Interacting with characters is as simple as walking up to them and clicking on them; our first mission was given to us by a Commander Brandon, who ordered us to go topside and destroy a "hellrift," through which demons were still emerging. Like a first-person shooter, the game uses the W, A, S, and D keys to let you move and the mouse to attack and use your special abilities. The game's interface we saw may not be indicative of the final game, but the version we played also offered a row of special abilities at the bottom of your screen that could be activated either by clicking on the individual icons, or by selecting them as the "active" ability to be used with the mouse.
