I want to play a ship, that only has that sole giant village killer on it. It'll be slower than cold molasses going up hill in winter, have a slow turn rate, and a one shot magazine, no turret turn radius. Pilot and captain have to get on target together, it can elevate up and down. Boooom! Giant shell ejects out of a side breach, tumbling to the ground while a cloud of smoke temporarily obscures the ship for 5 seconds, new slug loaded, Fire! It would be the ship killer.
Man, that be a super fun gun to use, knock stationary ships out of capture points with a single shot from a super vulnerable ship.
