''Border Down'' is a side-scrolling [[shoot 'em up]] set in a futuristic setting.<ref name=":3" /> Centuries after humans have colonized Mars, hostile aliens begin attacking the planet. The Mars defense force mobilizes and launch a new type of [[Unmanned aerial vehicle|unmanned aircraft]]. The player takes on the role of a pilot, controlling the aircraft through a remote control interface.<ref>{{Cite web|url=http://www.grev.co.jp/border_down/story00.html|title=Prologue|date=2003|website=G.rev|archive-url=https://web.archive.org/web/20170106100451/http://www.grev.co.jp/border_down/story00.html|archive-date=6 January 2017|url-status=live|access-date=4 August 2018|language=ja}}</ref><ref>{{Cite web|url=http://www.grev.co.jp/border_down/story01.html|title=R.A.I.N|date=2003|website=G.rev|archive-url=https://web.archive.org/web/20170106162118/http://www.grev.co.jp/border_down/story01.html|archive-date=6 January 2017|url-status=live|access-date=4 August 2018|language=ja}}</ref> The game's name is derived from its "border system".<ref name=":3" /> Each stage has three parallel variations, or "borders" of varying difficulty. The player starts on the easiest border ("green"), and if they lose a [[Life (gaming)|life]], drop to "yellow", and then finally the difficult "red" border.<ref>{{Cite web|url=http://www.grev.co.jp/border_down/rule.html|title=Border|date=2003|website=G.rev|language=ja|archive-url=https://web.archive.org/web/20160820181448/http://www.grev.co.jp/border_down/rule.html|archive-date=20 August 2016|url-status=live}}</ref><ref name=":0" /> If the player loses a life in the red border, it is [[game over]], though a [[Continue (video games)|continue]] option can be unlocked through repeated play. Each border is slightly different from the others, usually featuring other enemies and modified stage layouts and backgrounds. The final stage and ending are determined by the amount of time spent in each border during a playthrough.<ref name=":3" /> The Dreamcast version also features a "Remix mode" with new enemy attack patterns.<ref name=":0" />

The ship's main weapon can either be fired as a continuous barrage of bullets by holding down the fire button, or as a set of homing missiles by tapping it.<ref name=":3" /> A power meter slowly fills up over time which determines the strength of the ship's weaponry. It can also be boosted by destroying enemies.<ref name=":0" /> This meter can also power a secondary laser attack, which has an additional function of canceling out any boss attack, reflecting it back at them. Using the laser comes at a cost, as it drains the meter and therefore weakens the main weapon.<ref name=":3" />
