The Rail Gun is the artillery military unit of the Future Era. It is unlocked through the Extended Gaussian Distribution, and is the last unlocked unit of the Future Era. It is trained in the Rail Gun Range.
This is the very first artillery unit in the game that has high stats compared to other previous ages artillery units.
Versatile artillery unit in attacking matters. Works as the counter of all reactive armor units (Assault Tank, Battle Fortress, C.R.A.B. Mech and Augmented Samurai) as power shot skill ignores some defensive skills. Can target flying units unlike any other artillery unit, so it's not totally vulnerable against those.
Very low movement and recharge skill makes the rail gun ineffective against both ranged and fast units or miscellaneous combos.
