The best-received of the three Animorphs games, this RPG made much better use of the series' extended cast and universe. Battles play out similar to the Pokémon series, with turn-based battles and "capturing" morphs.
This was one of a handful of games to use the Ubi Key (Concept), a special item that could be found in-game and sent over to another Ubisoft game that supported it, and unlock special things.
