The Facility is an underwater lab designed for advanced research. It was used to research the artifacts and is a battlefield to many battles. This Facility was used to house one of the artifacts. In this area, water fills up most of the level, with one strong jump pad at the bottom right of the level to boost you up and another at the middle left area, also to boost you up.
