NetherRealm Studios and WB Games' "Injustice: Gods Among Us" DC Comics fighting game is only about a month away from release, and new content continues to tease game features to players. A new video on Amazon Germany's listing for the upcoming release boasts a "Blackest Night" downloadable content preorder bonus, with a Black Lantern costume for Batman and a special Zombie Mode that presumably turns the roster into the shambling undead, similar to NetherRealm's zombie mode in "Mortal Kombat."

While images of the skins and zombie mode have been shown before, the "Blackest Night" preorder bonus is only available in the US via Best Buy. Other preorder bonuses include a "Red Son" content pack with a preorder from Gamestop, while Wal Mart grants an "Arkham City" skin pack and a bonus copy of "Mortal Kombat Vs. DC Universe."

Check out the "Blackest Night" trailer below.

"Injustice: Gods Among Us" hits stores April 16 for PlayStation 3, Xbox 360 and Wii U.
