Positech’s long-awaited real-time strategy supernova Gratuitous Tank Battles has finally been released for Windows PC through Steam.

Retailing at at temporary 10% discount, the game will set customers back £13.49 until 24th May, after which it will hike up to the standard £14.99 price point. While that may seem fairly hefty for an indie release, it’s worth bearing in mind that the game’s spiritual predecessor, Gratuitous Space Battles, originally cost an equivalent of around $23 US, putting it roughly on par with Gratuitous Tank Battles‘ marketing model.

Gratuitous Tank Battles is a highly-anticipated hybrid of both the tower defense and real-time strategy genres, bringing two seemingly disparate, yet unerringly compatible schools of thought together in one explosive package. Set in an alternative future in which the First World War was never resolved, players are kitted out with a bombastic array of Mechs, lasers and, of course, tanks. With one’s devastating arsenal of weaponry in tow, what ensues is a series of frantic, unabatedly tense skirmishes across a wide variety of terrains and environments, with players being forced to think several steps ahead of the curve in order to triumph over adversity.
