Blast line

A blast line is a boundary on a stage that a character cannot cross without getting KO'd. Some stages have blast lines that are accessible by simply walking into them such as Mushroom Kingdom II in SSF, or Skull Fortress in SSF2. Other stages have large blast lines due to their large area such as.

There are four blast lines, usually referred to as "bottom"/"lower", "left", "right", and "upper"/"higher" (alternatively, "north"/"south"/"east"/"west"). The bottom blast line can also be referred as the "pit" and the upper blast line can also be reffered as the "ceiling." Characters KO'd via the upper blast line are either Star KO'd or Screen KO'd.
