Giant Digger

Giant Digger (Korean: 자이언트 디거) is a steel linear synchronous motor (LSM) launched roller coaster located in Lotte World Adventure Busan, South Korea, built by Mack Rides. Lotte World Adventure Busan began construction in May 2019, and Giant Digger was supposed to open alongside the park in May 2021. However, the coaster was delayed 3 months until August 2021, then further delayed until March 2022 due to delays in manufacturing and safety testing as well as COVID-19 pandemic related risks. On March 31, 2022, Giant Digger opened to the public alongside Lotte World Adventure Busan itself. The coaster is located in the Underground Zone area of the park, which is themed around a mining town where ogres live.
