Border Down was G.rev's second independent game (though they did subcontracted work on other titles, most notably Ikaruga and Gradius V), released after Sega's official discontinuation of the Dreamcast console.
Starting a tradition that is continued in Gradius V, this game introduced an online-ranking system.
