In GTA Liberty City Stories, the rock contains a small dock and a stairway leading up to the lighthouse from the dock, as well as various trees and shrubbery scattered about the island. However, in GTA III, Portland Rock is completely barren and devoid of any vegetation. Also, in GTA III, the stairway and dock are absent, possibly due to a storm or because of improper maintenance. The rock is unreachable in Grand Theft Auto III. If the player manages to reach it, he will be forced to slide down the island and in to the water.
