Dragon Buster Famicom

Dragon Buster (ドラゴンバスター, Doragon Basutā) is a platform dungeon crawl action role-playing arcade game that was developed by Namco in 1984 and released in 1985. It runs on Namco Pac-Land hardware, modified to support vertical scrolling. In Japan, the game was ported to the Family Computer, MSX and Sharp X68000; the latter version was later released for the Virtual Console in the same region on November 18, 2008. Dragon Buster has been ported for the PSP and is available as part of Namco Museum Battle Collection. It was followed by a Japan-only Famicom sequel, Dragon Buster II: Yami no Fūin, and was later followed by the PlayStation game Dragon Valor, which was both a remake and sequel.

The game featured side-scrolling platform gameplay and a "world view" map similar to the later Super Mario Bros. series. Dragon Buster was also the earliest game to feature a Double jump mechanic, and one of the first to use a visual health meter.
