Hellfire (ヘルファイヤー?) is a 1989 arcade game developed by Toaplan. It was later ported to the Mega Drive and the PC Engine CD-ROM², the latter under the name Hellfire S. Hellfire S contained notable differences from the other versions, including a remixed, more orchestral soundtrack, animated cut scenes, and the replacement of the leading male character Lancer with a female character called Kaoru (voiced by voice actress Yumi Tōma).
