Nintendo in Japan will be starting a campaign that would allow players who can beat Metroid Zero Mission the fastest to win a Metroid-themed Game Boy Advance SP housing shell. The campaign, running from June 15 to July 15, offers two ways to win the custom SP shell--Speed Ranking, a contest to see who can run straight through the game the fastest, or Perfect Ranking, where the player who beats the game the fastest while collecting all items wins. A total of 80 players will be able to win the prize. Additionally, Club Nintendo members in Japan will also be able to purchase the shell, starting August 10.
