Custom Robo N64

Custom Robo is sort of a sci-fi action take on Nintendo's own collect-and-battle style Pokemon titles. In the game's story mode, you slip into the role of a young boy who has just built his very own toy robot who goes by the name of Lei. Together with your cousin, you head down towards Robo Station to take part in a giant Custom Robo battle championship that takes place in the local Holosseum. The ultimate goal is to improve your skills so that you can defeat the champion Custom Robo builder of them all, Mamoru. Gameplay involves robo customization and frantic action battles in confined 3D arenas. Followed by a sequel.

Sequel to the Japan-only N64 mech battle game. Graphically and gameplay-wise Custom Robo V2 is the splitting image of its predecessor. Whereas the first game had only one quest, players get to choose from two scenarios this time around. Both storylines are set exactly a year after the first Great Robo Cup. Technological enhancements have brought forth new Robos, new weapons and parts -- but also new, more advanced rivals. Players once again slip into the role of a young boy who wants to prove to the world that he is the best Custom Robo fighter in existence. The ultimate goal is to improve your skills so that you can defeat the champion Custom Robo builder of them all.
