MIT Mystery Hunt 2020 was the 40th iteration of the MIT Mystery Hunt, with kickoff occurring on January 17th, 2020. Run by Left Out, the hunt began with a live wedding ceremony of two of the team's members, before proceeding into the customary opening skit. The hunt revolved around a fictional theme venue known as Penny Park. Due to a decline in popularity, the park was on the verge of shutting down. In an attempt to get it back up and running again, the newlyweds, mascots of the park, and owner of the park all recruited the attending teams to fix problems within the park's regions, thereby generating something known as Buzz, which would in turn draw more people to attend.
