Space Rangers HD takes place in 3300AD. Our galaxy is invaded by the Dominators, combat robots that come under the influence of an alien technology. The player finds themselves in a living, breathing world where they can engage multiple activities: fight in space and hyperspace, buy and sell goods, accomplish government missions, liberate planets from the Dominators in 3D RTS battles and complete text adventures leading to unique plot twists and rewards. The game ending is not set and players may find a victory of either side at the end. Everything depends on the actions taken in this developing world where anybody can live the life of a pirate as well as that of a hero.
