Worst Family Fun Vacation Ever (Act 2-2) is the second chapter of the second Act in Bulletstorm's campaign.
The chapter sees Gray and Ishi making their way through a tourist attraction called the "Terror Dome", where families and participants could control Mechatons, robotic versions of the Hekaton, in a large model-scale city from elevated platforms, where they could make the Mechaton rampage through the model city, smashing the buildings and shooting lasers out of the Mechaton's eyes.
While entering the model city, the two pass by a row of Mechatons; Gray notices that one is missing. After fighting through the set, they run into a ramaging Mechaton.
