Battlefield 5 will feature a number of singleplayer "War Stories," including one—The Last Tiger—that's presented from the Nazi point of view. That's a tricky bit of business: as the unequivocal, universal bad guys in human history, Nazis shouldn't be the heroes of any story. 

As franchise design director Daniel Berlin told Eurogamer, the solution is to make the characters face the consequences of their actions. The developers wanted to do a "tank-specific war story" for Battlefield 5, and there is no more iconic tank from that era than the Tiger, so that was the obvious choice to build it around. But the German tank, as he said, "comes with the German perspective."
