Batman: Arkham City - Nightwing Bundle

Nightwing remained in Wayne Manor during the events of Arkham City, and guarded the manor from armed intruders. During Protocol 10, Hugo Strange sent a number of TYGER Guards to Wayne Manor to kill Batman's allies and uncover more of his secrets. However, Dick was training in the Batcave, and was able to fend off the TYGER Guards until the GCPD arrived.
