B-System is a 2D horizontal scrolling shoot em 'up, developed by little-known Sprite and originally released as shareware in 1997 for Windows PC.While it takes elements of the classic horizontal shmups, it is very different than most. Well, the playthrough is Boss Rush type; that is, it lacks normal enemies and linear levels, there are only bosses in each stage, which must be defeated one by one.Another peculiarity of B-System is that the design of all bosses looks like sea creatures with destructive attacks and weaponry.It is known that it had a port for the Sharp X68000 computer, and that from version 3.0 it became freeware. It can be downloaded from the author's original web-site.In this sample, play and pass the first boss of B-System and here below I leave the link to download it for free:Note:To download it, press the numbers in blue on the web-site and unzip the file once downloaded.Link to download free B-System: https://web.archive.org/web/20070307041744/http://chinchilla.xsrv.jp/game/bsys/taiken.htmThanks for watching the video.
