Heh, the first Primary Objective is getting Nathaniel Black to the War Chief, but taking his uncle (Kanyenke) to the War Chief works just as well. Though I think that the War Chief is a little confused when I arrive there with Kanyenke ;) The actual main objective in this level is destroying one of the two enemy Town Centers. And I pick the left one because there's more resistance at the Town Center on the right. As soon as I get controle over the little village, I manually destroy the War Hut as fast as possible in order to trigger reinforcements (They arrive at the bottom of the map). It's just a matter of quickly getting a shitload of units to the enemy Town Center. Also, the moment I start attacking the Town Center, the enemy reinforcements show up but I don't bother with them. Thanks to Cortez for pointing out to me that I shouldn't bother killing the enemy War Chief, which I did in previous attempts ;)
