Railgun Cannon

Overview
The Railgun Cannon, or simply Rail/Railgun, is an original defensive building from The Conquerors Mark II and sadly it isn't in any other games of the series. The Railgun is the strongest and most expensive building in TC Mark II, it deals enough damage to kill a Mothership in a single hit, and, surprisingly, has a really fast reload for the amount of damage it does.

Usage
The Railgun Cannon is a defense building, although it's HP isn't high at all, it's the supremely the most damage dealt to enemies. It's damage can almost rip any building and units off the way. Placing one or two of these should enough to protect against offensive units. Somehow, still didn't recognize that if the railgun can one-hit kill to Mobile fortress. Sadly it can be destroyed by ICBM Nuke, but still didn't know it will survive a fire nuke. But make sure no units, nukes or even tanks and planes destroy these. It's so expensive due to it's damage but medium HP.
