Lol, no I spent like 40 hours bumming around making all the sidequests the letters, the hostages, races etc and after like 20 hours I found I could get the Sniper rifle to take the Outposts by stealth, you need to take 4 by stealth to unlock some abilities... running all you want and one more I cant remember.
My final was not killing him, I think eating and after that we went to that little room to put the ashes there and after that he said something like THIS KINGDOM IS YOURS BUT THE HELICOPTER IS MINE!
So I grabbed my rocket launcher and boom, but I´ve never wanted to kill him... good people.
I sided with the , and she was a , she killed the teenage girl and said mean things to my character so I rocketed her ass.
I think you mean the easter egg final, or you had the same final than me?
