SDCC 2018 was rife with a ton of fun setups that attendees could be a part of, like the DC Universe Harley Quinn Chaos Room. Attendees were treated to a wise-cracking security guard, who spoke to visitors as if they were inductees seeking treatment for their mental illnesses. Much like a haunted house setup, visitors were taken through the experience while wearing white coveralls and exploring, well, you'll see.
The security guard was awesomely in character, and the walls of the first room were adorned with creepy Joker masks. Inside the room, participants were given a bat to beat the living crap out of a Joker dummy, which was supposed to be some sort of creepy "therapy" related to Harley's obsession with the Joker. Not gonna lie, it looks pretty fun.
