Gratuitous Tank Battles is a unique take on tower-strategy mechanics, created by a man who clearly has a strong attention to detail. This article will be covering both the base game, released this past May, and its expansion The Western Front, which is being released this today on Steam. Both are developed by Positech Games, which is more or less known as Cliff "cliffski" Harris. At first glance, GTB appears to be a standard tower defense game covered in a fine finish, but things quickly become more complicated. For a bit of background reading, we do also have a preview of the game which goes over the basics from a different point of view.
