Within the floor right below the Battleship's deck were a series of rooms specialised for offensive tasks.
They were all similarly designed rooms. Each room was a large oval, and occupying most of the space was a large container.
The container was shaped like an egg, with the front attached to a barrel that poked out of the ship's hull. There was a mechanism within the barrel where an artillery shell could be inserted.
The shell was metallic, reaching fifty centimetres in length, with its insides containing a series of pressurised volatile gases. Inside, thanks to the mixture, they will remain stable while pressurised.
But the moment they come into contact with outside air and the pressure drops, they will combust, corrode, and melt through the contact surfaces.
"Pressure!" A Cooter Clansman shouted as a team of four inserted pressurised mist into the egg-shaped container, infusing as much psychokinesis-powered mist as possible. "Stable!"
