Makers of the recent Fujiko: 10-Billion-Dollar Goddess! pachi-slot machine, Heiwa, are closing out their celebration of the 40th anniversary of Lupin III TV anime with a "Great Chase" web campaign. Japanese players can create a police officer avatar, and chase Lupin's love interest/nemesis Fujiko Mine for a chance to win digital wallpapers, screensavers, an anniversary set of Lupin III anime, and even a chance to go to Las Vegas.
Only residents of Japan are eligible for the prizes, but the Great Chase is still a fun site to play around with. The campaign runs through the end of the month.
