*Static* "Clone TK-3864, do you read me? This is captain Rex. I'm being held prisoner by general Grievous. SOS! Bring reinforcements! hurry!--" *Static* After receiving this call, you rush to the given coordinates, where you are met by the four armed Kaleesh cyborg himself, Grievous. Now, you have no choice but to battle him yourself. But watch out! The separitist general might have a trick up his sleeve.
The cutscene in the beginning is about 3-5 minutes, ut after that, the intense battle against Grievous starts. Use the WASD and Arrow Keys to work your way through Grievous' ship, the Invisible Hand! This took me a long while. A heart and a Star (or a follow) would be nice. Much Credit to LucasFilm and Disney.
