Rules can’t be more simpler, All you do post how you taken the hill from the Poster and became king of the hill.
Poster 1: I push Op off the hill.
Poster 2: I punch Poster 1 and he runs off
Poster 3: I kick Poster 2 in the groin and he rolls off.
And so on.
PS. Don't do something excessive like launch nukes at someone who just planted a flag in the hill its supposed to slowly build up over time from small things to own the hill to finally epic stuff
Was walking down the the road when i saw a giant hill, walked on top of it and planted my flag. I'm king of the hill now.
