When a fight does break out, it largely takes place on automatic. You control one character at a time, attacking with special combat manoeuvres ("feats"), grenades, or Force powers, while setting up to two others to behave according to one of three predetermined scripts. You can pause the action at any time with the White button to rethink your current strategy, and switch between characters at will with the Black button. While it does seem painfully arbitrary at first, and has a few obvious issues, such as an enemy being able to connect a melee attack against you despite the fact that you're running like hell in the other direction, you'll get used to it quickly, especially if you're conversant with the d20 system the game is based upon.
