A little snippet on the PC controls:

During our time in The Hinterlands, we had a nasty run-in with some demons of the Fade. Using the WASD keys for movement, we charged our maul-wielding warrior into the fray, activated one of his abilities via the sleek PC action bar and smashed an enemy square in the face, incapacitating it for a short time. Unfortunately our rogue, a ranged character with a crossbow, was himself the target of some stab-happy monsters. So we quickly switched control over to our tank by clicking on her portrait, and commanded her to taunt the nearby enemies. All was going well – until our party got annihilated by the spellcaster demon, who wiped us from afar with a giant beam of magic. Ouch.

Round Two. This time, we knew we had to focus the caster demon and prevent it from destroying the whole party. As soon as it spawned we switched to the Tactical View by scrolling back on the mouse wheel. With a top-down perspective of the battlefield, we paused the game to plan the attack and strategize on a deeper level. Our rogue dealt bonus damage as long as he was at a higher elevation than his target, so we commanded him to move to a nearby hill. We set our tank to taunt the mage to draw its attention, freeing up our caster and warrior to dish out some damage. After our plan was set in motion, we resumed the action.
