The help says: "I need to destroy the other two buttresses." ... "I need to destroy the other two buttresses the same way I destroyed the first one."
I can remember I destroyed the first one by climbing on it and smashed the blue thing on the top. Since 3 hours I'm trying to destroy the other buttresses, but it doesn't work. I can't get to the top of them. Could somebody help please. I'm despaired
Thx!
