Command & Conquer 3 features returning aspects of gameplay from the previous series. The player oversees the action, ordering multiple units to move and attack targets. The construction yard, a moveable base, is the central platform from which the player constructs other structures. Certain structures can then produce units and resources are needed in order to fund the continuous building of structures and units. Typically the player's primary goal is to defeat an enemy by assaulting and destroying their base, while defending their own.
