Batman: Arkham Asylum - Crime Alley DLC

This is a Pack/Addon released in 2010 for Batman: Arkham Asylum, requiring the base game. It introduces the "Crime Alley Challenge Map," a new arena focused solely on testing your established combat and stealth skills against waves of thugs. A distinctive feature is that enemies can grab wall-mounted pipes to arm themselves during encounters. This content expands replayability but adds no new story elements.
