I seem to be stuck on this mission, can you skip it or must it be completed in order to do the final battle with Vader.
I saw some multi players on youtube and they only have to take down 3 of the walkers, I tried it and had to do at least 5. Of course usually the generator explodes by the 3rd one, and the tow cables break constantly. Could you skip the climbing up the legs on the first one and just shoot it with a ship? Or do something else, the flying vehicles are incredibly hard to steer just like in 1.0....
I can't do multi player so is this playset just unfinishable for me?
