The combat is simple button mashing at its core, but Buck's basic combo system and fruit-based projectile weapons make the fighting amusing, though monotonous hordes of similar enemy dinosaurs eventually put a chill on the fun. Buck is the main character, and both he and Sid take part in Ice Age's more action-packed sequences their on-foot levels typically mix combat, puzzle-solving, and exploration. Ice Age has a lot of variety in its gameplay, and each of the six playable characters offers a different experience. For example, the game never properly explains explain why Sid decides to adopt the dinos, or why Buck is seeking revenge on a dinosaur. Unfortunately, the characters' motivations are a bit incoherent at times, which leads to plot confusion. When Sid decides to adopt a litter of baby tyrannosaurs, the broody sloth is subsequently taken by the babies' mother, and it's up to you to rescue him with the assistance of the herd and Buck the weasel.
The game's plot is loosely based on that of the movie and features the same cast that fans will be familiar with.
