Kaitei Daisensou is a sideways-scrolling shoot-em-up for one or two-players. Each player takes control of a submarine and must shoot their way through the game's six levels as they are attacked from both beneath the water in which the submarine moves (by enemy subs, gun emplacements, mines etc.), as well from above the water-line, by boats, jet fighters and helicopters. Numerous power-ups can be collected to boost the sub's meagre fire-power.

This is a superb game, created by the ame 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 two further R*Type sequels were released for home consoles (see R*Type Series section for more info).

The title of this game translates from Japanese as 'Great Underwater War'.

This game is known in outside Japan as "In The Hunt".

NAG, the game designer didn't like shoot'em ups with forced scrolling. The idea of the submarine came one day when it feel asleep in a park and was woke up by the sound of a near fountain.


There are four endings to the game. You get two of them if you beat the game in 1 Player mode without using a continue or using at least one.
The other two endings are obtained by playing in 2 Player mode. Once you beat the last boss, both players will have a battle. If either win, you get an ending, but if you let the timer run out, you get another ending.
