Custom Robo: The sport of tomorrow. In the not-too-distant future, competitors battle customized robot warriors in holographic battle arenas. Victory is determined not only by fighting skill but also by how well Robo Commanders design their robot gladiators, so players need both brawn and brains to survive.The bulk of Custom Robo Arena takes place in holographic battle arenas called "holosseums." Players pit their Custom Robos against one another in fastpaced, melee-style combat. Each Robo can be outfitted with different parts, from arm-mounted guns and bomb launchers to specialized pod weapons that have their own unique behaviors. Some pods pursue the opponent, while others lie in wait for the enemy to draw near. Players customize their robots by swapping out weapons, legs and body frames to create the ideal combination of attack, speed and defense to suit their gaming styles.Outside of the battle arenas, Custom Robo Arena plays like a role-playing game in which players walk through the futuristic city setting and interact with other characters as they struggle to win the Custom Robo championship. The multiplayer aspect pits two players against each another in the holosseum. Battles can be played using Multi-Card Play or Nintendo Wi-Fi Connection and, if only one player has a game card, using DS Download Play.
