MAP23: Tower in the Fountain of Sparks IV (BTSX-E2)

MAP23: Tower in the Fountain of Sparks IV is the twenty-third map of the second episode of Back to Saturn X. It was designed by Xaser and uses the music track "Mystproj" by Sarah Mancuso. This level is the fourth and final of the episode's hub interludes, and contains no monsters, items, or secret areas.

Essentials
Turn left then left again to see a red spine wall, which will lower as you approach. Go through it and cross the water pool ahead, then follow the grass steps east and north until you reach a dark tunnel that goes down to a wooden bridge. Cross the bridge to reach a cave full of lava, carefully follow the stone paths until you reach the north end of the cave then go through the doorway here and follow the path back to the now-destroyed tower (the lava at this particular point is not harmful). Head through the opening in the east wall and turn right, then follow the path as it passes through a metal passage before leading you back outside. Go north at this point to a UAC logo and turn left, then pass through the opening on your right to go down to a building with flaming windows. To the right of this building is a second structure - go inside it and drop down the dark hole to finish the level.

Secrets
There are no official secrets on this map.
