I may have a solution to unlock this without climbing to the top of Wayne Tower. In my game, as soon as I jumped on a Gorilla in the Zoo, with Wonder Woman, the achievement popped.
I *think* this is because I was playing co-op, after completing the story, and the second player was already on top of Wayne Tower as I jumped on the Gorilla with Wonder Woman. As first player I had never been on top of the tower.
Can anyone test this? If it really is a glitch, it should be easy to reproduce: First, bring Player 1 to the zoo, near the gorillas. Change to a female character. Player 2 flies to the top of Wayne Tower. Once player 2 is in position, Player 1 jumps on the Gorilla.
Please comment if you can confirm or deny, or learn anything else about it.
