I used to play this on another forum. Here is how it works. There is a hill and your objective is to find a way to take it from the person who currently has it by getting through whatever defense they have, then set up your own defense for the next person to get through. Death is never permanent if you are killed when someone takes the hill from you.
So I will start:
I claim the hill and surround it with ten-foot-high electrified barbed wire.
My hill.
