Tower defense with a side of physics-based destruction is the order of the day with the launch of Zen Studios' CastleStorm -- Free to Siege, now out on mobile platforms. The game play -- Vikings vs Knights in medieval warfare, blowing up castles with heavy artillery -- was inspired by childhood memories of building and destroying Lego castles.
And it's, well, free, so there's your in. Check out the launch trailer for a better idea of how this all goes down.
Also, expect to hear more about CastleStorm - Definitive Edition coming to PS4 and Xbox One soon.
