“Watercave” was created as part of a so-called “multi-planet” map that allows players to travel through the “Stargate” to various planets, which usually differ largely in their appearance and layout to offer interesting gameplay twists within a single game level.
The map is set within a halfway flooded underground cave, which is adorned with crystals on the ceiling, colorful fireflies, and caustics coming from the moonlight which breaks through a small hole in the ceiling of the cave.
