What are Invizimals? They are animals that you have to capture, train and fight. Of course, there are a lot to collect and you gotta catch 'em all. The interesting part of the game though is how you actually track down these feisty critters. Using the included PSP camera, you scan your surroundings for traces of invizimals. Once found, you lay your trap and capture the rouge beasts. The game uses visual triggers to determine where Invizimals will appear; for example, to capture your first Invizimal, you will need to find a red surface.
