After the fortification of the island in 1942, a 16-inch artillery defense cannon was left to rust in the elements. Recently upgraded and improved by Project Janus forces in an attempt to weaponize Aetherium, this battery now serves as a devastating trap, providing you have the necessary power, as the cannon now shoots out an Aether Beam, the muzzle flash acting as a singularity that slows enemy advancement, and pulls any zombie enemies that are present within the deck area beneath the cannon up into the beam before they are vaporized.
