Warner Bros has just made the new  2016 Batman vs Superman Batsuit and Batmobile free to PS4 and Xbox One players, alongside the New 52 skin pack.
The PC version doesn’t look like it has the same deal, as yet, but given the issues with that build and that there are still plenty of disgruntled gamers on PC, I’m expecting them to do the same on that format, if not add more free stuff to sweeten the deal.
