Join the Brotherhood of Steel, a technological revival group dedicated to restoring the world to its former prosperity through science and whatever means necessary. Take part in a quest to reawaken long-dormant technology in order to defeat a powerful enemy in the one of a kind Fallout Universe. Each mission involves various hostile obstacles that must be overcome using tactical skirmish warfare. The player controls up to six detailed characters in the single player mission-based campaign or they may use their chosen squad online in multiplayer battles. Squad-members improve with experience, increasing their skills and earning perks. Many varieties of weapons, from handguns to rocket launchers, allow the player to lay waste to his enemies. In addition, the fighting isn't limited to pedestrians, as squad-members may take the action to the streets with armed vehicles.
