The film Sea Monsters is based on the National Geographic CGI documentary of the same name, in which the earth’s undersea habitat from millions of years ago is depicted as a dangerous environment with many predators keeping the ecology intact.
Players control six different prehistoric aquatic reptiles, each with uniquetrengths and limitations. The majority of the time is spent on exploration. The creatures must hunt prey, avoid or defeat enemies, solve secret puzzles, and eventually discover a way to leave the dangerous seas.
The stylus is used to control the movement of the creatures. They can dodge with a quick tap on the DS or a swing on the Wii, then enter combat mode to lock on targets and assault. In addition to ordinary strikes, the creature can dodge an incoming attack, which results in the appearance of a bite icon. Select it quickly, and the next strike will be significantly influential. Some monsters have unique powers that can be activated by tapping the sonar icon in the bottom left corner when it appears. This enables them to swim quietly, dig, break rocks, and jump.
The creature’s health (hunger), stamina, and oxygen levels are all monitored. Tiny organisms can refill health and energy, but oxygen requires a regular journey to the surface. Creatures can only dive to a depth of fifty feet. A big sonar can be seen on the bottom screen. Dangerous monsters have bright red spots, food has green areas, collectible fossils have yellow regions (required to unlock additional monsters), and portals have blue dots. Some fossils can only be discovered by slaying monsters or completing quests. New monsters get access to recent locations in the open sea via their talents, which serve as a hub. There are a few wildcard fossils to collect to unlock any monster.
The Wii and DS versions are nearly identical. However the Wii version has a multiplayer option in which players can race against friends across five different obstacle zones.
