Dungeon Siege 3 - Preview @ GameFront

Obsidian is pointing out a preview of Dungeon Siege III at GameFront after the recent press event at their offices:

Special moves are fueled by a bar called “Focus,” which appears beneath a character’s hit points. Executing moves drains it, as does blocking — instead of taking damage to HP when you block, you lose Focus points. Focus is restored by using standard attacks on enemies, and this has the effect of really pushing you to be offensive at all times. Most spells and moves have little or no charge up or cooldown times, either, creating an environment in which combat is almost non-stop. You might want to step clear and dodge an arrow or roll clear of an attack (possible by holding the block button and attempting to move), but for the most part, the key is to combo enemies with melee attacks leading into different special moves.
