Border Down

A horizontal Shoot 'em up developed by G.rev and released after the "death" of the Dreamcast

Borders   

Instead of having lives, Border Down features three borders: green (easy), yellow (medium), and red (hard). Each border is a different take on the current stage with alternate enemy placement and backgrounds. Death causes the player to drop down to a more difficult border. Dying on the red border results in a game over.
