Batman: Arkham City Armored Edition is set to be released this holiday season, though there has been no specific release date so far. The Armored Edition will feature Batman and Catwoman wearing Battle Armored Tech ( cleverly abbreviated as B.A.T.), which has a meter that can be filled up as a player fights. Once the meter is full they can unleash B.A.T. mode, which allows the player to dole out more damage.
There are some more features in Batman: Arkham City Armored Edition. When the player is doing investigative work, they can now look through the Wii U Gamepad to find evidence. Rather gimmicky, but certainly interesting.
Be sure to keep an eye out for Batman: Arkham City Armored Edition near the end of the year.
