Some missions offer you more than one choice of ownship submarine-you may play the mission as the Akula, 688(I), or the Seawolf. Many missions strictly prohibit firing on the enemy as you are expected to mirror real life Cold War objectives and get in-get out without being seen.
The single missions range from search and rescue, battle group escort, tailing enemy boomers, spy missions, and general-purpose search-and-destroy. The campaign can be played from either the Russian or US side, so in effect there are two campaigns. Sub Command sports three training missions, 23 single missions, and one 14 mission campaign. The player commands one submarine: a United States Seawolf, a Russian Akula, or a 688(I). appeared in immediately after the terrorist attacks in the United States. Sub Command, subtitled Akula Seawolf 688(I) is a submarine simulator computer game designed by Sonalysts Combat Simulations and published for Windows systems by Electronic Arts in 2001.
