Released in 2007 for Wii and PlayStation 2, Sea Monsters: A Prehistoric Adventure is a simulator set in the ancient oceans of prehistoric Earth. Players take control of six distinct marine reptiles, each defined by different attributes such as speed, armored defenses, or powerful jaws capable of crushing prey. The game unfolds across six underwater zones within an inland sea environment that grows increasingly hazardous over time. Players must alternate between roles — pursuing prey as a hunter while also evading larger predators — and take on hidden challenges unlocked through exploration. The overarching objective is to find a means of escaping the dangerous waters, with the method left for players to discover through play. Each of the six creatures is mechanically distinct, encouraging players to experience the prehistoric setting from multiple perspectives across the course of the game.
