Kalran: Tales of the four nations/Excalibur grand railgun

Tactical Analysis

 * Rain of destruction: The superweapon of the UCAAF, the Excalibur Grand Railgun launches several shells of enchanted high explosives at a rapid pace, devastating everything they hit.
 * Precision strike: The Excalibur is set to fire each of its shots at a different specified target; the commander can choose to concentrate the shots on a single area or spread out the proton shots for widespread destruction. But it has to fire all of its shots at once.
 * Crushing void: In addition to the destruction of the immediate target area, the Excaliburss shots also creates a small black hole, with anyone near the blast being sucked in and crushed in the center, and if the black hole destroys a building the effect spreads. If used on a densely packed base, it can turn the entire base into a smoldering ruin.
 * Up to speed: While devastating, the Excalibur requires some time to load each shells, during which it must be protected.

Trivia

 * It is based on the proton collider from red alert 3, tremor agas from rise of the red, and the mjolnir and omega blitzer from act of war/aggression.
