Ice Age 2: The Meltdown is a puzzle platformer based on the Pixar movie of the same title. It is developed and published by Vivendi Games and follows the adventures of the saber-toothed squirrel Scrat, who is obsessed with acorns. The game features numerous scenes from the film and the player takes the role of Scrat as he interacts with characters that help him in his quest for more acorns. Apart from Scrat, characters such as Manfred the Mammoth, Diego the saber-toothed tiger, and Sid the Sloth appear in the game. As Scrat, the player explores different locations in the frigid environment and collects nuts along the way. Players can also try out the mini-games such as Whack-a-Possum, which stars Diego as well as another one involving a slalom, which features Sid. Scrat also appears in other item collection and target shooting mini-games.
Some of the many scenes included in Ice Age 2: The Meltdown feature swamps, the woods, and the home of the Pliosaur named Maelstrom. Players can control Scrat to perform a variety of movements such as run, hop, jump, kick, spin, climb, and throw objects at enemies. He can also swing from one place to another using ropes or cling to walls. On some occasions, Scrat can play dead in order to elude his opponents.
