Zombiedood used to host this event quite frequently. He would start at the top.
IF you go to Ali's arena and in the middle top glass box area thing, there are warp signs that I believe lead to a mountain.
That mountain was the event area.
Now everyone climbs up only allowed a weapon. (MCMMO CONSIDERED)
So everyone has their weapons and about 30 second-1 minute warning/climb time is enabled. After that all hell breaks loose.
When you reach the top you were faced with I think like a mini parkour challenge.
Once you get in all you do is reach the top knock the person off then count to 10.
After 10 you go ahead and say, "I am now King of the Hill"
And you win. :P
