From Introduction: This product contains four sets of maps—a map of the island itself; a map of the natural cave with a secret passage to the first level of the base; a map of the first level of the base (also accessible by swimming through a tunnel in the cove); and a map of the second level of the base. The four maps can be used in isolation or as a set. Within each set includes full color maps with and without labels and printer-friendly black and white maps with and without labels.
