Stoneshill Kill/Defend the King.
First, after the gate is knocked down everyone dies (lol), and respawns in the throneroom. And well same rules as in an ordinary LTS with a lil twist:
both sides have leaders.
agathians have their king, masons have a siege commander (or general or something like that) and well both sides aim is to kill the leader of the opponents. which side achieves that first wins the round.
the equippment for those leaders, aswell as their stats are the same like the normal king of stoneshill.
