New Event: Skeleton Run

Run and survive! In this arena, the skeletons here don't shoot, they run to kill. These skeletons are faster and stronger than any zombies you've ever encountered. And you have to survive from them.
If you choose to compete, you must survive countless waves of skeletons for 5 minutes. The more you kill, the better your chances. As you move on from wave to wave, your reward increases, but so do your skeletons.
Do you wish to take on this challenge?
(Note: Friends may help you by shooting arrows from the tops of the towers, but they do not earn any rewards. If they wish to compete alongside you, you all must split the reward.)
