kaiteids: MAME ROM Information.


Kaitei Daisensou (c) 1993 Irem.

A 6-level, 1- or 2-player shoot'em up in which the player takes control of a submarine. Kaitei Daisensou is a superb game, created by the team behind the legendary "R-Type" series. The superbly-rendered graphics are very similar in style to Irem's "R-Type Leo", released a year earlier. Kaitei Daisensou would prove to be Irem's last 'traditional' arcade shoot'em up, although 2 further R-Type sequels were released for home consoles (see R-Type Series section for more info).
