The King's Run. Whomever pulls the flag from its stand becomes king of all the land. You must defend your crown at all cost. With attackers coming in fast, you must be faster to get to safe territory. Should the attackers get your crown, all is lost.
You (the defense) control a string of bases near the edge of your lands. The Crown(the flag) starts at the farthest base. It will take a coordinated effort to bring it to your final stronghold, all the while your territory diminishing to the advancing offense. Push back the invading army and restore glory to your King and Crown!
