New Batman: Arkham Knight story DLC appears to have been leaked ahead of an official announcement due later on Wednesday.
Batman News has been sent the image below, which advertises a 'Red Hood Story Pack' as a GameStop pre-order bonus.
At the same time, the retailer is teasing plans to make a "big announcement for a big game" on Wednesday, with a blurred out image which appears to match the one sent to Batman News.

Harley Quinn story DLC was confirmed as a pre-order bonus by retailers last month. "Utilise her unique weapons, gadgets, and abilities," reads Amazon's product listing. "Plus, contains 4 Exclusive Challenge Maps."
The PC, PS4 and Xbox One game was originally set to arrive later this year, but in June publisher Warner Bros. delayed the Batman Arkham Knight release date to 2015.
