'''''Border Down''''' is a horizontally [[scrolling shooter]] video game developed and published by [[G.rev]]. It was released in Japanese [[Amusement arcade|arcades]] in April 2003 on [[Sega NAOMI]] hardware, and was ported to the [[Dreamcast]] later that year. The story takes place in the future where humans are defending their [[Mars]] colony from an invading alien attack. The game employs a "border system" where each stage has three variations of different difficulty. The player starts on the easiest variation, and is lowered to a more difficult variation with each subsequent loss of a [[Life (gaming)|life]].

Producer Hiroyuki Maruyama was heavily inspired by [[Taito]]'s shooter ''[[Metal Black (video game)|Metal Black]]'' (1991) and founded G.rev with ex-Taito employees specifically to develop a shooter of his own. The team of five did subcontract work to gather funding and build their skills programming [[SEGA NAOMI|NAOMI]] arcade hardware. Among the projects they worked on were Treasure's ''[[Ikaruga]]'' (2001) and ''[[Gradius V]]'' (2004). Due to lack of funds, they were not able to realize all the ideas they conceptualized for the game. ''Border Down'' was released to mixed reception, but was commercially successful and continues to maintain a steady interest from shooter fans. G.rev went on to make other shoot 'em ups including ''[[WarTech: Senko no Ronde|Senko no Ronde]]'' and ''[[Under Defeat]]''.
