Batman Arkham City Mad Hatter Side Mission Walkthrough - The Tea Party

After saving the reporter Vicki Vale, you might have noticed that while you were speaking with her, a strange figure with a tall hat was watching you.

You get communication from Alfred that they have found a cure for the disease.

Side Mission: Unknown
Collect cure deployed by Alfred

Alfred: Good news, Master Bruce. I believe we have identified the cure. Mr. Fox has manufactured enough to heal you and is working on a larger batch for Gotham people.

That is good news! you wont have to infiltrate the steel mill anymore nor deal with Joker and Harley, and the people of Gotham will be saved. Go to the cure drop off point to collect the cure.

The drop off point is atop a roof in Park Row to the North of Ace Chemicals Building. It is guarded by thugs. Beat them, then get the cure from the box and inject yourself with it.

Batman collapses. It was a trap!

You wake up in a weird room around a dinner table surrounded by guys wearing bunny masks. The Mad Hatter, Jervis Tetch, is on the head of the table. He tells you how he planted the idea in your head about the cure to lure you to him. He will put a special hat on you designed to control your thoughts and make you do everything he says.

Follow the on screen prompts to struggle against Mad Hatter's hypnotic mask.

You find yourself on some weird giant clock. You are attacked by Mad Hatter's thugs. defeat all of them. They are not armed so you shouldnt have much problems dealing with them, except perhaps, geting dizzy from all the motion that is going on. use special combo multi ground takedown when possible. When mad hatter  shows up, tackle him to the ground and beat him. Take off the mask he put on you. This will complete the side mission and give you the "Stop the Clock" achievement.
