Futuremark Games Studio announced that their tower defense game Unstoppable Gorg is now available via Steam for PC and Mac, and via App Store via iPad - the Xbox 360 is coming later this year. In Unstoppable Gorg you defend our solar system from the relentless march of a fearsome alien race by sending satellites into orbit around planets, moons and space stations. Unlike other tower defense style games, in Unstoppable Gorg you can move your satellites even after you have placed them. When the Gorg armada attacks you can move your satellites around their orbits to best defend against each wave, a convention defying mechanic that brings new vitality and interaction to the tower defense genre. A new trailer is now locally mirrored.
