Crystal Cavern is a map for the Gem Grab game mode.
Crystal Cavern is formed with a long wall extending from the left side and a bulkier block on the right side. The block on the right is not connected to the wall and can be used as a narrow passageway.
Closer to the center, there are large blocks that have bushes close to the players side that extends to the inner path. On the sides of the center there are medium sized hiding spots with a small block protruding out.
