From the box cover:
The game is a surface naval simulation which allows the player to operate single ships or a task force made up of ships, from the United States Navy (USN), Royal Australian Navy (RAN) and Royal New-Zealand Navy (RNZN), or the Imperial Japanese Navy (IJN) in the South Pacific during WWII. It was designed to run under PC-DOS or MS-DOS, version 5.0 or higher. The specific historical setting was the series of ferocious naval engagements fought around the largest island in the Solomon Islands chain, Guadalcanal, in 1942
The player could start a single engagement (historical battle or battle made from the editor) or play in the campaign mode. The whole campaign game was centered on the Guadalcanal campaign, although a number of single engagements (Kula Gulf, Vella Lavella, Empress Augusta Bay) happened elsewhere in the Solomons. In campaign mode, the player was given full control over the naval forces of either side based in Espiritu Santo (Allies) or Rabaul (IJN). The player's goal was to capture Guadalcanal providing its ground forces with sufficient reinforcements and supply, while trying to disrupt the other side's own efforts. Apart from ships, the player had the control over land-based air assets which could be used as real-time reconnaissance. The whole campaign was in real-time (which could be accelerated or slowed down at will) and any encounter between two enemy naval forces would result into the computer asking the player if he wanted to play it in the simulator mode.
