How can you beat illidan on the frozen throne?

Answer 1

I cant really remember because i havent played the game in a long time but i will do my best to tell you well first you must have arthas activate the switches that open the entry to the frozen throne but it takes time so illidan or his Allies will attempt to attack you and take control of the switch. So you will have to take control of the switches first or if illidan controls them your mission to save the Lich king will fail and the Lich king will die so you must take control of the switches when you do the entrance to the frozen throne will open and then you enter then you finished!! Oh yeah, and then it will show 2 clips one of illidan being slayed at the hands of Arthas and the second Arthas becoming the new Lich king
