Strike fear into the hearts of Xbox Live's ne'er-do-wells this week with a handful of discounted Batman-themed items. Outside of a few Avatar props, select DLC for Batman: Arkham City has also been reduced in price.

The Nightwing Bundle Pack and Robin Bundle Pack have both been knocked down to 360 MS Points ($4.50) from their respective usual 560 MS Points ($7) asking price. Each comes with a handful of character skins and exclusive challenge maps, and unlocks each character for play in all of Batman: Arkham City's challenge maps.
