You have to admire Warner Bros. In this era of DLC backlash, especially when it seems designed to trick the consumer into spending more money beyond the retail price of the game, the way they've brazenly marketed the
Harley Quinn Revenge Pack as "the final chapter of
Batman: Arkham City" is a sight to behold.
They are selling the true ending as premium DLC, perhaps the most offensive use of premium DLC, and they're proud enough of that fact to, essentially, brag about it. Amazing.
Whatever your particular thoughts are on the issue, the fact remains that
Batman: Arkham City's final chapter will send players back into Arkham City to stop whatever nefarious plan the Joker's number one fan is working on. During the two added hours of gameplay, players will switch between Batman and Robin and do whatever is necessary to stop Harley Quinn.
Furthermore, if you haven't yet picked up
Batman: Arkham City, you should definitely check out the
Batman: Arkham City Game of the Year Edition that is out on May 29th. It includes all previously released DLC (
Catwoman Pack, Nightwing Bundle Pack, Robin Bundle Pack, Challenge Map Pack, and the
Arkham City Skins Pack along with
Harley Quinn's Revenge Pack).
If you already own the original, then on May 29th you can simply download
Harley Quinn's Revenge Pack for $9.99/800 Microsoft Points.
