LawBreakers is not a post-apocalyptic shooter.
It is a shooter. It does star a group of Marine-like soldiers out to gun down people in the name of justice and it does take place in the future. But creator Cliff Bleszinski is adamant that this isn't a standard futuristic, kill-streak kind of game. As the mastermind behind Gears of War and Unreal Tournament, he knows all about those. Instead, LawBreakers takes place in a post-catastrophe world: Human experiments on the moon cause it to shatter, which triggers devastating earthquakes and breaks gravity in certain spots. Humanity rebuilds, bigger and better than ever, and then violent gangs begin to attack the new world. The LawBreakers are deployed to fight the gangs, using super-human supplements and special maneuvers made possible by the low-gravity zones.
