This game is a masterpiece and adds a complex new battle system which I think is the best ever. You can summon clones to fight with you, hijack a tank and mow down a squadron of droids. it also introduces a machine-gunning character who can mow down anyone who tries to come near him. The levels are in 3 branches which have you follow Grievous, Ventress and Dooku. It all ends in a climactic battle where you face the Zillo Beast after a large battle. Perfect levels with a great battle simulation will have you replaying most levels over and over again. 8 out of 10 lego studs. Peace!
