B1A4 scream their faces off during a tour at 'Lotte World's 'Zombie Factory'

After enjoying themselves on a few of the usual rides like a roller coaster and the viking, B1A4 paired up for their first main course, the 'Zombie Factory'! Leader Jinyoung and maknae Gongchan were first up and began their course with their hands held tight, but still couldn't help screaming their faces off and running. The same fate befell on Sandeul and CNU, as the two kept yelling at each other to hurry up (It seems Baro wasn't able to participate in the filming).

The second course was a 'Zombie Nightmare Coaster', during which the members also had to answer mission questions about their comeback while on the ride. You can watch the first part of B1A4's 'Lotte World' adventures above! The full clip capturing their experience will be uploaded next week!
