Wayne Tower

Wayne Tower is a building that appears in every main Arkham game. Before Batman: Arkham Knight, it was simply a part of the Gotham skyline. It's located on Miagani Island, Central Gotham.

The Arkham Knight Incident
Batman entered Bruce Wayne's office on the top floor several times throughout the night. His visits usually consisted of asking Lucius Fox for technical advice, such as tracking the Arkham Knight through his broadcasting channels. While visiting, Batman could engage a security scanner hidden in a bust of Shakespeare that, after verifying Batman's identity, caused two Batpods to rise from the office's floor. One Batpod contained a spare V7.43 Batsuit while the other contained a supply of spare/replacement gadgets, one of which was a prototype Disruptor that Lucius was developing. When these Batpods were unearthed, Lucius joked about Batman "spoiling the surprise" while showing off the then unfinished Disruptor.

Later, Fox dropped off the radar, which caused Alfred to worry about his safety. As the top floor was locked, Batman had to enter throughout the building through the elevator. Upon arrival, he learned that the security was breached by Hush, angry at the Waynes for ruining his life. He took down Hush, and requested Fox to lock him into "the vault", as he couldn't brought onto the GCPD without harm to Bruce Wayne, as not only did Batman have to unmask in front of Hush to subdue him, but Elliot now perfectly resembled Wayne himself.
