On the other side of Arkham City, Commissioner Gordon and a GCPD S.W.A.T. team were busy attempting to reach a group of undercover police officers, who had previously been taken hostage by the Penguin, but ultimately saved, despite a few casualties, by Batman. They had taken control of the Iceberg Lounge, and the Museum, using it at a base-site.
Batman reached the front doors of the Iceberg Lounge as Gordon was leading the men out, the rest of the S.W.A.T. team handing out armour to them.
"Jim." Batman greeted him.
"Batman." Gordon replied, "Hell of a mess you and your kids made here." He said, gesturing around.
Batman didn't reply, instead he surveyed the scene around them, as the undercover officers slipped on the armour, and strapped it down tight. "I warned you, sending in a team was dangerous." Batman replied sternly.
"And I told you I wasn't going to ignore this place." Gordon replied, walking away. "What happened here?" he asked as Batman followed.
The group was tightly knitted, led by Gordon and Batman across the courtyard.
"I infiltrated this place when I heard Hugo Strange was planning something here. Turns out I was right." Batman stated, taking a Batarang out of his belt and cutting through a wire fence.
"And?" Gordon prompted as he and Batman tugged the fence apart for people to slip through.
"Strange was planning something called Protocol 10." Batman replied. "Protocol 10 was to give authorisation to Arkham City's TYGER guards." He said, "To kill everybody inside Arkham City." He added grimly.
Gordon stopped walking.
Batman stopped, and turned back to him, watching Gordon closely.
"Did you stop him?"
Batman remained silent for a moment, "No. I don't know why Strange didn't initiate Protocol 10." Gordon opened his mouth to reply, but Batman continued. "And now he's gone, so is his TYGER guard. But I will find them." Batman said firmly, putting Gordon in his place. "Let's get you, and your men out of here.
