As of now the pack was only available for those purchasing the Limited Edition of Batman: Arkham Knight, but is now downloadable for those with the season pass.
The New 52 costume is based off more recent DC comics, and also comes with new costumes for both Robin and Nightwing. This special suit looks much like the v8.04 suit, with the inclusion of a gold bat symbol.
In essence, it is the suit you acquire early on, without the battle damage. The Batsuit V8.04 is identical to the v8.03 suit in every way, with the added bonus of being in pristine condition, and never degrading with any wear or tear.
