Border Down

Border Down (ボーダーダウン) is a Sega NAOMI GD-ROM horizontal shoot-'em-up game developed by G.rev, released in 2003. It was ported to the Sega Dreamcast in the same year, with both a standard and Limited Edition released.

Border Down is a pseudo sequel to Taito's Metal Black. The games share certain enemy designs, story elements, gameplay mechanics and staff members. The Dreamcast version features both original and remixed layouts for each stage. The remixed stages also offer a new soundtrack. Sega Logistics Service announced it would end service on the arcade machines on March 31, 2017.
